Fraction to Decimal Calculator
This free Fraction to Decimal Calculator converts any fraction to a decimal instantly. Shows the simplified form and the mixed-number form where appropriate.
How It Works
Divide the numerator by the denominator. Example: 3/4 = 3 ÷ 4 = 0.75. For fractions with denominators that are not powers of 10, the result may be a repeating decimal (1/3 = 0.3333...).
When to Use Each Form
Fractions are precise but harder to compare at a glance. Decimals are easier to compare but may be approximations for repeating decimals. For cooking, construction, and most everyday math, decimals are more practical. For music theory, probability, and exact algebra, fractions are often preferred.
Simplified vs Unsimplified
A fraction is simplified when numerator and denominator share no common factors other than 1. 6/8 and 3/4 represent the same value, but 3/4 is simpler. Our converter always shows the simplified form.
