What this calculator does
This tool converts any percentage into its equivalent fraction, first expressing the percent as a fraction over 100, then simplifying to lowest terms, or converting a decimal percentage by first clearing the decimal point before simplifying.
Percent to Fraction = Percent ÷ 100, then simplify to lowest terms
Example: 37.5% = 375/1000 = 3/8
Example: 37.5% = 375/1000 = 3/8
Why decimal percentages need an extra step
A whole-number percentage like 25% converts directly to 25/100, then simplifies. A decimal percentage like 37.5% first needs the decimal point cleared by multiplying both the percentage and 100 by the same power of 10 (turning 37.5/100 into 375/1000), before simplifying to lowest terms, this extra step is where manual conversions often go wrong.
Frequently asked questions
How do I convert 37.5% to a fraction?
Write it as 37.5/100, multiply both by 10 to clear the decimal (375/1000), then simplify to lowest terms, giving 3/8.
Why does a decimal percentage need extra steps compared to a whole number percentage?
A whole-number percentage converts directly to a fraction over 100, but a decimal percentage needs its decimal point cleared first (by multiplying both numerator and denominator by a power of 10) before the fraction can be simplified correctly.
