How to Divide a Fraction by a Whole Number
To divide a fraction by a whole number — also written as a fraction divided by a whole number — use the keep, change, flip method:
- Keep the fraction as it is.
- Change the division sign to multiplication.
- Flip the whole number — write it as 1 divided by that number (its reciprocal).
- Multiply the numerators together and the denominators together.
- Simplify the result if possible.
Example — divide a fraction by a whole number: 3/4 ÷ 2
= 3/4 × 1/2 = (3 × 1) / (4 × 2) = 3/8
Why does this work? The reciprocal of any whole number n is 1/n. Dividing by n is identical to multiplying by 1/n — splitting something into n equal parts gives the same result as taking 1/n of it.
Not the Same as Dividing a Whole Number by a Fraction
Note: dividing a whole number by a fraction (e.g. 2 ÷ 3/4) is a different operation and gives a different result. This generator specifically covers dividing fractions by whole numbers (e.g. 3/4 ÷ 2).
