multiply the numerators (top numbers) together put that number on top, multiply the denomonators (bottom) together, put that number on the bottom---   5/8 times 4/7 is 20/56

Multiplying the denominators of all the fractions would be the easiest method.\n\nHowever, if the numbers are really big and you prefer working with small ones (e.g. if you do not have a calculator), you can first find the lowest common multiple (LCM).

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

Convert the fractions to a common denominator which is 24\n2/3 = 16/24\n3/8 = 9/24\n5/12 = 10/24\n\nThen add them up. \n16 + 9 + 10 = 35 or 35/24 \n\n35/24 = 1-11/24

subract 32 then divide by 1.8 (or mulitply by 5/9 --- same thing)

When adding fractions with the same denominator, just add the numerators and keep the same denominator:  x (which is 1x) + 3x = 4x/6\n\nSince 4 and 6 are divisible by 2, reduce this to 2x/3.\n\nWhen two fractions are equal, the top of fraction 1 times the bottom of fraction 2 equals the top of fraction 2 times the bottom of fraction 1.  This gives a new form of the equation without fractions.  Here;\n\n(x-3) times 3 = 15 times 1\n\n3x - 9 = 15   add 9 to both sides to get\n\n3x = 24   divide both sides by 8 to get\n\nx = 8

First change them to improper fractions to do this multiply the whole number by the denominator so in 3 and 7/8 you would take 3 times 8, once you got that you would add it to the numerator so\n\n3x8=24\n7+24=31\n\nso you have 31/8 for the first fraction\n\nrepeat this step for the second\n2x10=20\n20+9=29\n\nthe second is 29/10\n\nNow you must fine the lowest common denominator for both fractions, which means find a number both 8 and 10 divide into evenly. Both go into 40 evenly, so you want the denominator to be 40 on both fractions, to do this multiply the top and bottom of each so that the denominator is 40 so for the first fraction, 31/8 you would multiply both the top and bottom by 5.\n\n(31/8)x5=155/40\nand the second fraction\n(29/10)x4=116/40\n\nnow you can subtract them\n\n(155/40)-(116/40)=39/40

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

The fractions you wrote are actually already reduced fractions; i.e. the gcd(numerator, denominator) = 1\n\nif you were intending to multiply the three fractions, that simplifies to 13/50

You need to find the lowest common denominator, then add the numerators together.  This is the sum of them all, now you must reduce the fraction.\n\nin this case the lowest common denominator is 12.. why? because you can multiply each of them by a number to create 12.\n\nso 1/6 * 2 = 2/12, 2/3 * 4 = 8/12, and 1/4 * 3 = 3/12\n2/12+8/12+3/12 = 13/12\nthe answer is 1 1/12

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

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.

fractions into decimals\n\neasy way is 7/100 \ndivide 7 by 100 and you will get 0.07\n\ndivde mix fractions like 2 5/8\nchange into improper fraction 21/8\nthen divde 21 by 8 and you will get 2.625

Two very important things to know:  Anything times 1 is itself, and anything divided by itself equals 1.  So to create equivalent fractions, you can multiply or divide the top and the bottom by the same number without changing it's basic value.\n\nTry 3/4.  Pick any number, say 5.  5/5 is 1 because anything divided by itself is 1.  So, remembering that you can multiply anything by 1, you could multiply 3/4 by 5/5.\n\n3/4 * 5/5 = 15/20.  Now on a calcualor enter 3/4.  It's .75.  Now enter 15/20.  Also .75\n\nTo reduce fractions it works the same way.  Look at 8/12.  2 goes into both 8 and 12, so you can divide top and bottom by 2 without changing the value of the fraction.  8/2 is 4 and 12/2 is 6 so 8/12 is also 4/6.  Now 2 goes into both of those again, so if you do it again 4/2=2 and 6/2=3.  So 8/12 = 4/6 = 2/3.  If you put all of these into a calculator you will get .66666repeating for all 3 of them.

Multiplying by a fraction is like taking a fraction of something.  Example: 3/4 times 1/2 is like taking half of 3/4.  Since you didn't even have a whole thing when you started, and you are only taking a part of what you started with, you will have even less than a whole thing when you are done.
