Fraction to Percent Converter
Type a numerator and a denominator — the fraction becomes a percentage, with the decimal shown on the way.
Quick answer: 3/8 = 37.5% — 3 ÷ 8 = 0.375, and 0.375 × 100 = 37.5%.

The method
Divide the top number by the bottom number to get a decimal, then multiply by 100 and add the % sign. A decimal converts the same way: just multiply by 100 (0.625 → 62.5%). Going the other way — percent to fraction — divide by 100 and simplify: 75% = 75/100 = 3/4.
