Comprehensive Calculator Guide
This calculator divides the numerator by the denominator and multiplies by 100, giving the percentage with the decimal value and the fraction in lowest terms. 3/8 is 37.5%, 7/4 is 175%, and 2/3 is about 66.67% because its division never ends. Handy for homework and for turning “3 out of 8” into a clear percentage.
The method and repeating decimals
A percentage is a fraction over 100: divide, then multiply by 100 — 3 ÷ 8 = 0.375 → 37.5%. If you can make the denominator 100 directly, the numerator is the percentage: 3/4 = 75/100.
Fractions whose reduced denominator has only factors 2 and 5 end as decimals; others, like 2/3, repeat and are rounded. A numerator bigger than the denominator gives more than 100%.
