Two add two fractions, the denominators must be equal.\n\nThe first step is to convert the addend that is a mixed number (an integer plus a proper fraction) into an improper fraction. Do this by multiplying the integer part by the denominator and then add the numerator of the fraction.\n\nExpress the result as an improper fraction (fraction with value greater than 1) whose numerator is the sum you just calculated and whose denominator is the same as the denominator of the fraction part of the mixed number.\n\nFor example: 2/3 + 4 2/5 = 2/3 + 22/5\n\nNext, find the least common denominator of these two fractions, the smallest integer that contains both denominators as factors. For the example above, this is 15. Multiple both terms by (3*5)/15, which equals 1, and therefore does not change the value of the fraction:\n\n(2/3) * (3*5)/(15) = 10/15 (the 3's "cancel out" since 3/3 = 1)\n(22/5) * (3*5)/(15) = 66/15 (the 5's "cancel out" since 5/5 = 1)\n\nNow add 10/15 + 66/15 by adding the numerators and keeping the same denominator: 76/15.\n\nFinally, express this improper fraction as a mixed number by dividing: 5 1/15

Inversion means to flip the fraction.\nSame change flip\nkeep 8 or 8/1 the same, change division to multiplication, and flip the second fraction to 4/3 thus\n(8/1) * (4/3) =  (8*4)/(1*3) = 32/3  or 10 2/3 as a mixed number\n\ntosmith

Take the decimal number and multiply it by a number.  Then take the sum and divide it by the multiplier.\n\nI'm supposing you know the decimal number you want to express in a fraction.

When you have (a+b+c)/d, you can separate the terms of the numerator like so a/d + b/d + c/d.  If I do that and simplify, I get:\nx - (6/5) - (3/x).

Its an old arithmetic trick used when adding two large numbers.  You sum the first numbers digits, then the second numbers, ... etc, then take the remainder when you divide that sum by 9.  If the sum of the total's digits does not yield the same remainder, you made a mistake. For example:\n\n213+756+1148=2417\n2+1+3=6\n7+5+6=18/9 = 2 r 0\n1+1+4+8=14/9=1 r 5\nAdding remainders, we have 11/9=1 r 2.  But the sum of our digits in 2+4+1+7=14/9=1 r 5.  So something is wrong. Turns out the 4 should be a 1, 2117.  So its just an error correction method.\n\nSteve

You use cross multiplication.\n1/2, 5/8, 6/*, 3/4 \n\nYou multiply the numerator of one fraction to the denominator of the other fraction you're comparing it with. For example, you cross multiply 1/2 and 5/8.\n\n1*8 = 8 so lets say 1/2 got 8\n5*2= 10 so 5/8 got 10. Therefore, 5/8 is greater than 1/2

for the first one it's '1'. this is because of the AB'+1. since anything or'ed with 1 gives u 1. the whole thing turns out to be 1. same thing happens in the other bracket. so when 1 n 1 are ANDed u get 1.\n\nfor the second one remember ther are two terms. one is DE' other is (A+F) in the second bracket the (A+F) term has been complemented. when DE' is ANDed by itself u get DE' again. When DE' is Anded with (A+F) and it's complement u are able to actually factorize it so u can take DE' out and u get the or'ing of a term an it's complement inside. that is 1. therfore it evaluates to DE'. then (A+F) and it's complement gives a 0 when anded. oring everything left u get ED' as the final answer. if u need the working pls msg me

You find the fraction of a fraction by multiplying the top numbers and (separately) multiplying the bottom numbers.\n\nTherefore, the answer is 1/3 x 1/8, or 1 x1 over 3 x 8.  1 x1 = 1, and 3 x8 = 24, so you wind up with 1/24.\n\nWhen I first learned how to do this, I wanted to divide rather than multiply.  But you multiply the fractions, and, as I said, top numbers go with top numbers and bottoms with bottoms.  Good luck!!

I'm pretty sure it's the same as multiplying 2 fractions.  You just multiply across the top, then across the bottom, or in w/e order you like, and what you get is your answer.

The product is the answer in a multiplication equation.  The denominator is the bottom number in a fraction.  The simple way to find your answer is to just multipy the bottom numbers (5x4x7).  After adjusting the numerators, you can usually add the fractions.\nGood question. \nGood luck with your homework

I used to also. I'll try to give an explanation: forgive me if I go over anything you already know. Alright, think of it this way: you know how to multiply fractions, correct? Alright, so when you multiply two fractions, such as 1/2 and 3/4, you multiply the numerators (those are on the top) (1x3) and the denominators (those are on the bottom) (2x4) and you have your answer: 1/2 x 3/4 = (1x3)/(2x4) = 3/8. Dividing is just the opposite of multiplication. So if you were dividing 1/2 by 3/4, you just flip over the second fraction and multiply: 1/2 / 3/4 = 1/2 x 4/3 = 4/6. \nHere's an answer that's a bit more advanced but might help you understand this better (at least it did for me): if you have some number, a, over some number, b, it can be written this way: a/b. Now, if you divide it by some other fraction, c/d, it can be written this way: \na/b x 1/(c/d). This is the same as saying that when you divide 6/1 by, say, 2 (which equals the fraction 2/1), it is the same as if you are multiplying 6/1 (6/1, or six divided by 1, equals 6) by 1/2. See for yourself: 6 / 2=3, 6 x 1/2= 6/1 x 1/2 = 6/2 which when you reduce (divide top and bottom by common factor, in this case 2) it equals 3/1, or 3. \n1/(c/d) is the reciprocal of (c/d). The reciprocal basically means you flip the top and bottom: for instance, the reciprocal of 2/3 is 3/2, the reciprocal of 1/2 is 2/1, or 2, the reciprocal of 4/1, or 4, is 1/4, etc. So if you flip over c/d, you get: a/b x d/c, which if a=1, b=2, c=3, and d=4, is exactly the same as what we had above.

That simplifies to 3[2x-1]>12\n\n[2x-1]>4\n\n2x-1>4    2x-1<-4\n\nx>5/2  or x<-3/2\n\nWhen you have absolute values, you have to look at both ends of the spectrum

There is no simple trick for the addition of two numbers. You will have to calcuate their actual value and then add them. So for you example you would have to go to 4 + 8 = 12.

lets say the fraction is 6/12\nfind a number that goes into 6 and 12 evenly\nin this case 2,3 and 6 do but you always go with the biggest number that can go into both.\nsix goes into itself once and into twelve twice so the answer is 1/2\nlets say the fraction is 13/6 its an improper fraction and needs to be reduced. thats the case when ever the top number is bigger then the smaller number.\ndivide the bottom number into the top number this time it goes in twice but you still have one left over. you put whatever is left over on top of your original bottom number and the answer is 2 1/6\n\nhope it helps

okay first convert mixed numbers to improper fractions so you have 9 2/7 and that equals 7*9+2=65\n\nso you have 65/7*7/8\n\nmultiply 65 by 7 and get 455\nthen 7*8 and get 56\n\nso you have 455/56\nconvert the improper fraction to a mixed number take 445/56 and you have 8 with a remainder 7\nso 8 and 7/56= 8 1/8  check ya later ♥

Those are mixed numbers containing whole number and a fraction.\n8 1/2=8+1/2=8.5\nSimilarly 1 1/4=1+1/4=1.25 and others.

alright - the fractions you have given me are called unlike fractions which means they have a different denominator. to compare fractions the first thing you need to do is make them like(same denominator) -now,a fraction remains the same if you multiply the numerator and denominator with the same number. So look at your denominators-3,5,4,8. you need to find a number that is a common multiple for all these numbers-if you look at it, you dont see any immediate number as such-so just multiply all of these numbers to get their common multiple(ideally you should look for the lowest common multiple) which gives 480. now,multiplying the numerators with the corresponding numbers we get the following fractions: 320/480,192/480,360/480,300/480.\nnow that you have all the like fractions, though these may look different, they are actually same as the original fractions that you gave me. all you have to do now is arrange them in ascending order of numerators which gives:\n192/480 , 300/480 , 320/480 , 360/480\nnow writing the corresponding original values,your answer is:\n2/5 , 5/8 , 2/3 , 3/4\n\nthis is one method,another method involves direct division and then comparing the value, but you will get the same answer
