How it works
Divide the top number by the bottom number to get the decimal. Multiply that decimal by 100 to get the percent. Three eighths, for example, is 0.375, which is 37.5 percent.
The bottom number cannot be zero, because a fraction with no denominator has no value.
Worked example
3 out of 8 is 0.375 as a decimal, or 37.5 percent.
Questions
What are the numerator and denominator?
The numerator is the top number, and the denominator is the bottom one. In three eighths, three is the numerator and eight is the denominator.
Can I turn a percent back into a fraction?
Yes. Put the percent over 100 and simplify. Thirty-seven and a half percent becomes 37.5 over 100, which is three eighths.
Why would I need a percent?
Percents are easy to compare. Seeing that a score is about 37 percent makes it simpler to judge than the raw fraction.
