Fractions were always the hardest for me, and I still have to do a quick check! Rather than go through each one (add, subtract, multiply, subtract, I’ll send you a really good web site. http://www.mathleague.com/help/fractions/fractions.htm

I dont know how old you are so you might not have learned this. I will try to explain a good way to multiply stuff if you dont have a calculator. \nYou can split up the multiplication to make it easier for yourself. instead of doing 13 x 375, you can make it \n(10 x 375) + (3 x 375). This is basic factoring. The first one is pretty easy, you just add a 0 on the end.\n3750 + (3*375) is what you have to find now. If this is also too hard, then you can split it up further. \nYou can do (3 x 300) + (3 x 75) and the first one isnt that hard to do. 3 x 300 = 900. then 3 x 75 is 225, but if that is still too hard then just do it again. Pick a number that you can multiply easily (such as 50), and split it up again\n(3 x 50) + (3 x 25) = 150 + 75 = 225.\n\nNow comes the hard part though. (Not that hard). You have to add all the totals up.\n  (10 x 375) + (3 x 300) + (3 x 50) + (3 x 25)\n= 3750 + 900 + 150 + 75\n= 4875

In fraction if the denominators are the same, just add the numerators and copy the denominators, then reduce to lowest term as needed.\n\nExample: 1/2 + 3/2 = 4/2 or 2\nThe numerators are 1 and 3,  adding them will give 4. Then just copy the denominator which is 2. That makes it 4/2, which you need to reduce to lowest term. So 4 divided by 2  (to reduce to the lowest term) so the answer is  2.\n\nIf the denominators are different, then find a common denominator (the least number that can be divided by both denominators) then divide it with the denominator and multiply with the numerator. Then when your numbers are already expressed on fraction with the least common denominator, proceed to adding the numerators and copy the denominator.  \n\nExample:\n\n1/2 + 2/3   (the common denominator will be 6)\n>>1/2 becomes >> 6 divided by 2 = 3  X 1 = 3 -->> 3/6\n>>2/3 becomes >> 6 divided by 3 = 2  X 2 = 4 -->> 4/6\n\nProceed to addition:\n3/6 + 4/6 = 7/6 (divide 7 by 6 to get the lowest term) = 1 and 1/6 is the answer.\n\nGood luck!♥

Start with demonstrating the multiplication of fractions through physical models.\n\nSplit a rectangle in half.  That is 1 x 1/2... because you are counting that one thing 1/2 time.\n\nThen split the 1/2 into 1/2.  1/2, counted 1/2 time, is 1/4.  See it?\n\nOK, so... through whole numbers you have already demonstrated (and they should already have shown true comprehension of the idea) that division is the inverse of multiplication. So...\n\n\n1/2 divided by 2/3 is the same as 1/2 x 3/2 because that is the inverse. Division of whole numbers is a reduction of value... division of fractions is an increase of value.\n\nAlso, try this with decimals.\n\n1/10 divided by 4.\n\n1/10 divided by 4/1.\n\n1/10 x 1/4 = 1/40.\n\n1/40 = 0.025.\n\n   ____\n4 |0.1     = 0.025.\n\n25 x 4 = 100\n\n2.5 x 4 = 10.0\n\n.25 x 4 = 1.00\n\n.025 x 4 = 0.100\n\nStart to see the pattern now?

Do you mean (2x^2 + 3x + 1/ 2x^2 + x - 3) for your first fraction?  I'm going to assume you do.\n\nFirst, factor each numerator and denominator:\n\n2x^2 + 3x + 1 = (2x+1)(x+1)\n\n2x^2 + x - 3 = (2x-3)(x+1)\n\n4x - 4 = 2(2x-2)\n\nNow let's look out our multiplied fraction, rewritten using our factors we just found:\n\n[ (2x+1)(x+1)2(2x-2) ] / [ (2x-3)(x+1)(2x+1) ]\n\nNotice we can cancel out the (2x+1)'s and the (x+1)'s, to get:\n\n2(2x-2)/2x-3\n\nANSWER:   2(2x-2)/2x-3

The way to divide fractions is to first convert any mixed numbers to improper fractions and then multiply by the reciprocal (the reciprocal is what you get when you switch the numerator and the denominator). Thus for your first question, you have 3 5/6 ÷ 3 1/2 = 23/6 ÷ 7/2 = 23/6 * 2/7 = 46/42 = 23/21 or 1 2/21.\n\nTo add fractions, you must first convert all the fractions so that they have the same denominator, then simply add the numerators. So for your second question, 1/3 + 1/2 + 3/4 = 4/12 + 6/12 + 9/12 = 19/12 or 1 7/12.\n\nIf you're trying to add mixed numbers, you may do so either by converting to improper fractions and then adding, OR you can save yourself some time by adding the fractional portion and the whole number portion seperately, and then recombining. Conceptually, a mixed number is A b/c is A + b/c and so you're really just using the commutative property of addition to rearrange your numbers before adding. Thus for your third problem: 12 1/4 + 5 1/4 + 8 1/2 + 7 1/4 = 12 + 5 + 8 + 7 + 1/4 + 1/4 + 2/4 + 1/4 = 32+5/4 = 33 1/4

Multiplication and division are basically just a matter of memorization.  I know if you're just learning it, its hard.  I remember having trouble as well when I first started.  But keep at it.  It will get frustrating at times, but keep at it.  The problem with math is that as you go farther, you need to remember everything you've already learned.  But otherwise, it can be real easy.  Just keep at it and you'll do fine.

Do you want to do it by calculator or by hand?\n\nIf by calculator, just take the top number divided by the bottom number to get your decimal:\n\n>> Fraction:  3/4 = 3 ÷ 4 = 0.75\n\n>> Mixed number:  Put the whole number to the left of the decimal point, then divide the top number by the bottom number to get the portion to the right of the decimal:  Example 8 2/3 = 8.666...\n\nIf by hand, multiply top and bottom to get 100 in the bottom (if possible) ... for example, multiply 3/4 by 25/25 to get 75/100 = 0.75.\n\nIf it's not possible to get 100 in the bottom, then just do long division to get the decimal.\n\nHope that helped a little!\n\n~ ♥ ~

Steve, Fractions are easy and here is how to figure them out.\n\n13/15 = ?/30.\n\nDivide the larger denominator by the smaller and multiply the answer with the given numerator. The answer will be ?. In the above question the larger denominator is 30 and the smaller 15. So divide 30/15 and the answer is 2. Multiply 2 with the given numerator, which in this case is 13. So 13*2=26. The unknown numerator ? is then equal to 26.\n\nLet us take the last problem 9/15=12/?.\n\nHere 12/9 gives us a decimal as an answer. We don't want that so we merely cross multiply to solve the problem.\n\n9/15=12/?\n9?=12*15\n9?=180 \n?=180/9\n?=20.\n\nThe unknown denominator is 20.\n\nHope this helps.

First compare the whole numbers.\nList them in order by their whole numbers. \nNext, if more than one has the same whole number, then you need to compare the fractions.\nTo compare the fractions, you will need a common denominator.\nAfter you have a common denominator, you just compare the numerators.\nExample:  List in order from least to greatest.\n5 1/2, 8 5/6, 3 7/8, 4 1/6, 8 3/4, 3 15/16\n\nFirst list them in order by the whole numbers.\nThe whole numbers are 5, 8, 3, 4, 8, 3\nIn order, they are\n3, 3, 4, 5, 8, 8  (Not so hard so far, is it?)\nNow go ahead and put the fractions with them.\n3 7/8, 3 15/16, 4 1/6, 5 1/2, 8 5/6, 8 3/4\nNow since you have two mixed numbers with 3, you must compare the fractions.\nFor the whole number 3:  Which fraction is smaller 7/8 or 15/16?\nTo compare them, you will need a common denominator.\nThe common denominator of 8 and 16 is 16.\nSince 8 times 2 is 16, you need to multiply the top and bottom by 2.\n7/8 = (7*2)/(8*2) = 14/16\nWe now have a common denominator.  Now which one is smaller, 14/16 or 15/16?  Since 14 is smaller than 15, we conclude that 7/8 is smaller than 15/16\nSimilarly for the mixed fractions with whole number 8:\nWhich one is smaller, 5/6 or 3/4\nHere the common denominator will be 12\n5/6 = (5*2)/(6*2) = 10/12\n3/4 = (3*3)/(4*3) = 9/12\nSince 9 is smaller than 10, 3/4 is smaller than 5/6\nThe answer is\n3 7/8, 3 15/16, 4 1/6, 5 1/2, 8 3/4, 8 5/6

I will try to explain step by step....\n\nA) x-2/3 + x+3/4=5/6\nFirst you would place like terms together;\nx+x-2/3+3/4=5/6\nThen try to make all the denominators equal.  Do this by thinking of what the denominators can all go into.  In this case, they can all go into 12 using whole numbers.  Since multiplying by 1 doesn't change the value, you can do that by multiplying the top and bottom of each fraction by the same number.  \n  So the -2/3 would all be multiplied times 4/4 giving you -8/12.  The 3/4 would all be multiplied times 3/3 giving you 9/12.  The 5/6 would all be multiplied times 2/2, giving you 10/12.\n\nThe equation would now look like;\nx+x-8/12+9/12=10/12\n\nYou then combine like terms;\nx+x=2x\n-8/12+9/12= 1/12\nSo your equation is now;\n2x+1/12=10/12\n\nSubtract 1/12 from both sides;\n2x=9/12\n\nAnd divide by 2;\nx=4.5/12 or 9/24\n\n9/24=3/8\n\nSo, the answer to A would be x=3/8\n\nAs for B...I'm not to good at word problems, sorry :)\n\n\nAnd NS in line 3 of your work, it should be -8/12 because -2*4= -8 not 8

So lets start with the first one. Make a division problem with 9.0 on the outside and 0.9 on the inside. 9.0 does not go into 0 but does go into nine. Raise the decimal and the answer is ten. It's a bit difficult to explain but here's your answers and when you go in next time ask your teacher for help::\n1. 10 \n2. 8\n3. 4.7\n4. 3.2\nOkay theres a few for you and you should be able to figure out the rest. For the next part you take what x is equal to and divide it by 1.2. So for\n13. 40.8/1.2=34\nAnd do the same for the rest!!\nGood luck!

ill explain. to subtract or add fractions, you have to get a common denominator. to do this, you have to find the lowest common multiple of the denominators of both fractions. so what is the lowest number that can be divided by 10 and 6 easily. the answer is 30 in this case. cuz 10*3 = 6*5 = 30.\n\nso now that you know what the denominator has to be, you have to convert each fraction to a fraction that has 30 as the denominator. so for 7/10, you can multiply top and bottom by 3 to get 21/30. its the opposite of reducing the fractions. think of it this way:\n7/10 * 3/3 = 21/30.   since 3/3 =1, youre just multiplying the fraction by 1, which doesnt change anything.\n(7/10 * 3/3) - (1/6 * 5/5)\n= 21/30 - 5/30\n= (21-5)/30.... once you have a common denominator, u can subtract the numerators.\n= 16/30\n= 8/15.\n\nhope this helped. let me know if u need more help.
