How to Use Fraction Multiplication Calculator
The Fraction Multiplication Calculator makes multiplying fractions effortless, with clear step-by-step output.
- Enter the Numerator and Denominator — Fill in the top (numerator) and bottom (denominator) fields for each fraction. For an integer such as 5, leave the denominator blank or enter 1.
- Add More Fractions (Optional) — Click + Add Fraction to multiply three or more fractions at once. The Fraction Multiplication Calculator handles any number of operands.
- Read the Result — The Fraction Multiplication Calculator instantly displays the simplified fraction, its decimal equivalent, and the mixed-number form when applicable.
- Follow the Steps — A step-by-step breakdown shows the raw product (before simplification) and the final reduced form so you can verify every detail.
Formula & Theory — Fraction Multiplication Calculator
The Fraction Multiplication Calculator is based on the standard rule for multiplying fractions:
a/b × c/d = (a × c) / (b × d)
For three or more fractions, the rule extends naturally:
a/b × c/d × e/f = (a × c × e) / (b × d × f)
| Symbol | Meaning |
|---|---|
| a, c, e | Numerators of each fraction |
| b, d, f | Denominators of each fraction |
Simplification
After multiplying, the Fraction Multiplication Calculator divides both the numerator and denominator by their Greatest Common Divisor (GCD) to produce the lowest-terms result:
GCD(numerator, denominator) = g
Simplified = (numerator ÷ g) / (denominator ÷ g)
For example: 2/3 × 3/4 → 6/12 → GCD(6, 12) = 6 → 1/2
Mixed Number Output
When the result is an improper fraction (numerator ≥ denominator), the Fraction Multiplication Calculator also shows the mixed-number form. For example, 7/4 is displayed as 1 3/4.
