Through performing the required division, fractions can be converted into whole numbers, decimal figures, or percentages when the numerator is divided into the denominator.

Tips & Warnings
As you are calculating percentages, you will frequently encounter situations where you don't seem to have enough numbers to move the decimal point over twice. In these cases, zeros are added to complete the conversion. In the above example of 8/4, the resulting decimal number is 2.0. Moving the decimal point over to the right once only gives your 20. To correctly convert this decimal number into a percentage, you need to move the decimal point one more time. In doing so, you will have to place a second zero after the number 20 so that the correct percentage is 200%.
