Fraction Calculator with Steps (Mixed Numbers)

Updated · Free · No sign-up · Runs in your browser

Type two fractions — like 3/4, a mixed number like 1 1/2, a negative like -2/5, a whole number or a decimal — and pick an operation.

The answer is shown in simplest form, as a mixed number and as a decimal, with the steps for homework. Exact integer math, so there is no rounding error.

Operation

Answer (simplest form)

13/6

Mixed number: 2 1/6 · Decimal: 2.166667

Steps

  1. 3/2 + 2/3

Worked examples

  1. 1/2 + 1/3

    • = 3/6 + 2/6

    → 5/6

  2. 3/4 − 1/6

    • = 18/24 − 4/24 = 14/24

    → 7/12

  3. 2 1/2 × 1 1/3

    • = 5/2 × 4/3 = 20/6

    → 10/3 = 3 1/3

  4. 5/8 ÷ 1/4

    • = 5/8 × 4/1 = 20/8

    → 5/2 = 2 1/2

How to add and subtract fractions

  1. Find a common denominator (multiplying the two denominators always works).
  2. Rewrite each fraction with that denominator.
  3. Add or subtract the numerators, then simplify by dividing by the greatest common divisor.

How to multiply and divide fractions

  • Multiply: numerator × numerator, denominator × denominator, then simplify.
  • Divide: flip the second fraction (its reciprocal) and multiply.
  • Mixed numbers: convert to improper fractions first — 2 1/2 = 5/2.

Mixed number fraction calculator

Type a whole number, a space and a fraction (1 3/4). Negative mixed numbers work too: -1 1/2 means −3/2.

Frequently asked questions

How do I enter a mixed number?

Type the whole number, a space, then the fraction: 2 3/4. For a negative mixed number type -2 3/4.

Does it simplify the answer?

Yes. Every answer is reduced to lowest terms using the greatest common divisor, and also shown as a mixed number and a decimal.

Can I use decimals?

Yes. 0.75 is read as 3/4 and 1.2 as 6/5, so you can mix decimals and fractions.

How do you divide fractions?

Multiply the first fraction by the reciprocal of the second: 5/8 ÷ 1/4 = 5/8 × 4/1 = 20/8 = 5/2.

Is the answer exact?

Yes. The calculator uses exact whole-number arithmetic, so 1/3 stays 1/3. Only the decimal line is rounded (to 6 places).
