A mixed number, 2 1/4, can be expressed as\n\n2 + 1/4\n\nThe decimal representation of 1/4 is\n\n0.25\n\nTherefore, the mixed number 2 1/4 is\n\n2 + 0.25\n= 2.25

first turn any whole numbers into fractions:\nex) 2 & 1/2 becomes 5/2 (2x2=4 +1=5 and the bottom number remains the same)\n5 & 1/3 becomes 16/3 (5x3=15 +1=16 and the bottom number remains the same)\n\nnext, if the bottom numbers are not the same, make them the same:\nex) 5/2 - 1/2 already has the same bottom number so you would simply subtract the top numbers 5-1=4 so the answer would be 4/2.  To simplify, divide 4 by 2. Answer is 2.\nex) 1/2 - 1/3 bottom numbers are not the same so you change them.  In this case, 2 & 3 have the number 6 in common so that is the number you will use on the bottom.  1/2 will become 3/6 (2*3=6 on the bottom & 1*3=3 on top) 1/2 will become 2/6 (3*2=6 on the bottom & 1*2=2 on top).  Now you have 3/6 - 2/6 = 1/6 which cannot be reduced.\n\nThe key to subtracting fractions is to get the bottom numbers the same by multiplying top and bottom by the same number.\n\nThe key to simplifying fractions is simply division.  If the top and bottom numbers can be divided by the same number so that.\nEx) 4/8 both are divisible by 2 which makes it 1/2\nIf the top number is larger than the bottom, you can get a whole number with a fraction.  First simplify as above and then divide, if there's anything left over (a remainder) place that over the bottom number to make the remaining fraction.\nEx) 75/9, both are divisible by 3 so reduce first. (75 becomes 25 and 9 becomes 3) the new fraction is 25/3 now break it apart further. 25 divided by 3 is 8 (3*8=24) that leaves 1 left over (25-24=3), place the 1 over the bottom number 3 and your final answer is 8 & 1/3\n\nHope this helps some.

in dividing fractions, you just multiply them by its reciprocal.\n\nso \n\n[(x+5) / (16x)]  * [ (4x ^2) / [(3x -2)] \n\nperform the operations: \n\n[ (x+5) / 4 ] * [ x / (3x-2) ]\n\nthe answer is:\n\n[x(x+5)] / [ 4(3x-2) ]

To multiply fractions, fundamentally the answer is the product of the numerators (top numbers) divided by the product of the denominators (bottom numbers).  For example,\n\n(2/3) * (3/7) = (2*3)/(3*7) = 6/21\n\nWhen any of the fractions contain whole parts such as the "4" in your problem, it does slightly complicate it.  Let me show you 2 slightly different ways to deal with this situation, you pick the one you like:\n\nYour problem can be rewritten as\n\n(4 + 2/7)*(8/11) =\n\n[4 * (8/11)] + [(2/7) * (8/11)] =\n\n(32/11) + (16/77) =\n\n224/77 + 16/77 =\n\n240/77\n\nOr you can do this shortcut, which converts the "4" to "elevenths" - multiple it (the "4") by the denominator (7) then add the numerator (2).  4*7 = 28, plus 2 = 30.  This will be your new numerator.  Now the problem looks like:\n\n(30/7) * (8/11) =\n\n(30 * 8)/(7*11) =\n\n240/77\n\nGet it?

You divide fractions by multiplying the reciprical... for example:\n\n1/2 x 8/3 = 8/6 or 4/3\n\nYou simply multiple the numerators together and the denominators together after that

3 divided by 2/4 is equal to 3 times 4/2.  To divide by a fraction, invert and multiply.\n\n3 divided by 2/4 is equal to 6.

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!♥

Well, 2/5 is already a fraction.  It is a "rational fraction," which means that it is expressed as a ratio, i.e. one number divided by another.\n\nYou can also express it as a decimal fraction.  Divide 5 into 2 by the usual means you do division and you will find that 2/5 = 0.4.\n\nYou can also express it as a percentage.  Just multiply the decimal fraction by 100: 0.4 x 100 = 40%.

Multiply the numerators together.  Then multiply the denominators together.  Just go straight across.  If you want, you can simplify the fractions in the beginning so that it's a bit easier.  Then if your answer isn't in lowest terms, I'd simplify that too.  Hope I helped!

To show you how to do it yourself..\n\nfor 8/7: 7 "goes into" 8 once so separate it as 7/7 + 1/7, 7/7 becomes "1" and "1/7" remains as a fraction.\n\nTherefore "8/7" becomes "7/7 + 1/7" which becomes 1 1/7.\n\nSimilarily, 38/6 becomes 36/6 + 2/6 which becomes 6 2/6.\n\nYou get to do the rest.... happy learning!

convert a % to a fraction by putting the number over 100.  For example, 34% is 34/100.  which is also .34 as a decimal.

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

Grab a caluclator and add.\nLet's see...the whole numbers are\n52 + 6 + 5 + 4 + 8 + 12 + 10 + 13 + 12 + 15 + 7 + 26 = 170\nNow add the fractions\n1/2 + 1/2 + 1/2 + 3/4 + 1/2 + 1/2 = 1 + 1/2 + 3/4 + 1 = 3 1/4\n170 + 3 1/4 = 173 1/4

Divide the numerator (top number of the fraction) by the denominator (bottom fraction number) then multiple by 100%

thats very simple to multiply a fraction you just multiply straight across. Numerator times numerator, denominator times denominator. \n\nEX: 1/2 * 1/2 = 1/4 or 2/3 *2/3 = 4/9\n\nTo divide a fraction its almost basically the same. First you take the "recipricol" of the second fraction. That just means you flip it upside down. Like so\n\nEX: 1/2 divided by 1/2 would become this. 1/2 * 2/1. \nnotice it becomes a multiplication problem now. So you work it jsut like a mult. problem\n\nheres another example to be sure. 2/3 divided by 5/6 would become 2/3*6/5 = 12/15
