Going from percent to fraction is easy.  Percent literally means "per 100" so just divide your percent by 100 to get a fraction.  For example, 16% = 16/100.  You can then simplify if you want, to get 16/100= 4/25.\n\n~ ~ ~ ~ \n\n66 2/3% = 0.66666.... or 0.6 (with a dash on top of the 6).  The fraction is 2/3.\n\nTo go from a repeating decimal to a fraction, it's a little tricky. Here's how you do it:  Notice how many numbers are in the repeating pattern -- in this case it's only the 6, so we have 1 repeating number.  Use this "1" to tell you that you need to multiply your decimal by 10^1 to solve.  (If our repeating decimal was 0.181818... that would be two repeating numbers and we'd need to use 10^2 to solve.)  Anyhoo, we have 1 repeating number, so take your decimal, call it x and take 10^1 times x minus x to solve:\n\n10x - x = 6.666... - 0.6666\n9x = 6\nx = 6/9 = 2/3\n\nAnd that's how you go from repeating decimals to a fraction!\n\n~ ~ ~ ~ \n\n18/15 = 120% = 1.20\n\n~ ♥ ~

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.

Just multiply:\n(X/3)(3/4 x) -(x/3)(3/5) + (3/4)(3/4x) - (3/4)(3/5)\n\nand simplify from there

Say you have 100 of something.  You want to raise it 20%.  You take 20% of 100 and add it to 100.  so a 20% increase of 100 is 120.\n\nIt is a little more difficult if you have a number like 19.  But then you just find out 20% of that by:\n\nX over 19 = 20 over 100\n\n19 x 20 = 380\n380 divided by 100 = 3.80\n3.80 + 19 = 22.80\n\n22.80 is 19 increased by 20%.

something like 3/4 to 75%? :\n\nDo the division and multiply by 100.

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!

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!!

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) ]

divide by a number and get the same number you are dividing by as an answer for example  \n49 divided by 7 =7

In multiplying you have to multiply the numerators and demoninators and simlify. and in dividing you have to find the resiprocal of the second # by switching the numerators and demoninators and then you multiply the #s. Peace!

To convert a fraction to decimal using a calculator, its just the top number (numberator) divided by the bottom number (denominator).\n\n1 ÷ 4 = 0.25\n\nTo convert it without a calculator, you can use equilavent fractions, which works for some easy denominators. Just change the denominator to a power of 10 (10,100,1000,...) by multiplying the top and bottom by the same amount, which keeps the same value of the fraction.\n\n1/4 = 1*25 / 4*25 = 25/100 = 25 hundredths\n\n25 hundredths ends in the hundredths column, so 0.25\n(thats the same as 2 tenths and 5 hundredths)\n\nYou can also work out any fraction into a decimal using long division, just proceed past the decimal as normal, putting in extra 0's\n\n1 ÷ 4 = 4 into 1 = 4 into 1.00\n\n4 ) 1.00\n\n4 into 1 goes 0 remainder 1\n4 into 10 goes 2 remainder 2\n4 into 20 goes 5\n\n0.25, keeping the decimal point in the same place\n\nThis always works, although you will need to decide when to stop for a repeating decimal such as 1/3\n\n3 ) 1.0000...\n\n3 into 1 goes 0 remainder 1\n3 into 10 goes 3 remainder 1\n3 into 10 goes 3 remainder 1\n3 into 10 goes 3 remainder 1\n3 into 10 goes 3 remainder 1\n.\n.\n.\n\n1/3 = 0.33333...

With a calculator. If you're trying to do it in your head, then it depends on how your head works. For me I multiply parts of the numbers and add them. If I'm trying to do something like 15X22 I'll multiply 10X22 and add it to 5X22. For me it's easier to break it down into easier equations.

This is actually elementary math. If you remember the order of operation, it helps. \n\nStep 1: Do the part of the problem in the parenthesis.\n  Example: (4/3)= 1.3333333333 (you get where this is going)\n\nStep 2: Take that answer and multiply it by the named multiplier.\n  Example: 1.33333 * 12= 16\n\nStep 3: Take the result of that transaction and devide it by the named devisor. For this method don't use the fraction way, and don't use a calculator. Do a basic devision problem like you were taught in the 3rd grade using the "bracket."\n  Example: 16/13 = 1  (13 goes into 16 1 time)\n\nStep 4: Subtract the 13 from the 16 and it will give you your remainder.\n  Example: 16/13 = 1   16-13= 3\n\nThe answer when written correctly isn't with a decimal but would look like this- 1 R3.\n\nAlso for a little note for this- Order of operation:\nP (parenthesis)\nE (exponents)\nM (multiply)\nD (devide)\nA (addition)\nS (subtraction)\n\nHope this helps!

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!
