To convert a fraction to a percentage, divide the top by the bottom to get a decimal, then multiply by 100. Three quarters becomes 0.75, then 75 percent. The percent sign simply means per hundred, so every percentage is a fraction with a denominator of 100.

How to convert a fraction to a percentage
First divide the numerator by the denominator to get a decimal, then multiply by 100 and add a percent sign. Two fifths is 2 divided by 5, which is 0.4, and 0.4 times 100 is 40 percent. The two steps can be combined: multiply the fraction by 100 directly.
Why percentages are just fractions
A percentage is a fraction whose denominator is fixed at 100. Fifty percent is fifty hundredths, which reduces to one half. Seeing percentages this way makes mental conversion easy: a quarter is 25 out of 100, or 25 percent, and a fifth is 20 out of 100, or 20 percent.
