The Conversion Formula

To convert a fraction to a decimal, divide the numerator by the denominator. For a mixed number, add the whole-number part to the decimal value of the fractional part.

Formula: decimal = numerator / denominator. For a mixed number a b/c: decimal = a + (b / c).

Frequently Asked Questions

How do I convert 3/4 to a decimal?

Divide the numerator by the denominator: 3 ÷ 4 = 0.75. The converter performs this division for you the moment you enter the fraction.

How do I enter a mixed number like 1 1/2?

Type the whole number, a space, then the fraction — for example 1 1/2. The tool adds the whole part to the fractional part, giving 1.5.

Why does 1/3 show as 0.333...?

Some fractions produce repeating decimals that never end. 1/3 equals 0.3333... repeating forever, so it is displayed as 0.333... to show the pattern.

Does this work for improper fractions?

Yes. An improper fraction such as 5/4 converts to 1.25 — the numerator is simply divided by the denominator regardless of which is larger.

Is this converter free to use?

Yes. The tool runs entirely in your browser, is free to use, and requires no sign-up. Your numbers are never sent to a server.
