to change fraction to percentage always divide the bottom number into the top number. Then move the decimal to the right 2 spaces.     56.25

What the...? I don't get that fraction....but uhh, to get the square root of fractions you take the square root of both the top and bottom, and then you simplify...that's all I got...good luck and God bless...

I don't know the rule... I don't even think there is one you jsut divide the fraction and see if it repeats... But to change a decimal into a fraction (if you can round the fraction to the hundreths-the first 2 numbers after the decimal-) but multiply the decimal by onehundred and then try to reduce...

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%.

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

first get a common denominator for the (1/x - 1/y):\n(1/x) - (1/y) = \nx/xy - y/yx = \nx-y/xy\n\nnow that we have 2 fractions in fraction form, we can reduce it to one fraction by multiplying the top with the bottom over the 2 middle sets:\n\nxy (x+y)\n-----------\nx-y (y-x)\n\n\nexpand or leave it as that

Divide 1 by 2/5 or \n1/(2/5) = 5/2

Simply multiply by 100.\n\nThe reason for this is simple.  We interpret percent as 1/100 so if we want to convert a fraction a/b to percent we have the following:\n\nc % = a/b ==> c * 1/100 = a/b ==> c = 100 * (a/b)\n\nYou may also want to convert a/b to decimal.  Although this is not essential.

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) ]

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.
