You divide the top by the bottom to find your percentage. It will most likely be a decimal.

25.You take 100 divided by 8 to get 12.5, this tells you how many parts of 8 are in 100. Then take 12.5 times 2 (which is the number of grams in 8 percent) to come up with the answer of 25.
1.00*100 = 100%
2/8 = 25% The easiest way I've found to do percents is cross multiplying: 2/8 = x/100 So to solve for x, multiply 2 times 100 (equals 200) and divide by 8 (equals 25). So 25/100 equals 25%. Works for anything... Another example: what is the percentage of 53 out of 976? 53/976 = x/100 So 53 times 100 (equals 5300) and divide 5300 by 976 (equals 5.43) or 5.43%.
Percents ca n be co nverted to decimals a nd fractio ns. Example: 50% = 0.5 = 50/100 or 1/2
It is: 0.5*100 = 50%
