Multiplying Fractions
including Mixed Fractions with Mixed Numbers

The product of multiplying fractions always results with proportion that increases if the factors are greater than 1 and no factors are equal to zero:

  1. 1 (one) multiplied by any non-zero fraction equals the non-zero fraction: 1/5 • 1 = 1/5
  2. 1 (one) multiplied by all non-zero fractions equals the product of all non-zero fractions not equal to 1: 2/3 • 1 • 1/2 = 2/6 = 1/3
  3. Fraction multiplication by zero equals zero: 2/3 • 5/8 • 0 = 0

The denominator of a fraction can never equal zero. A zero denominator is undefined math.

Dividing and multiplying fractions are each opposite math operations of the other.

How to Multiply Fractions

There are 3 steps for fraction multiplication:

  1.  Multiply all numerators.
  2.  Multiply all denominators.
  3.  Simplify fractions answers by reducing fractions to make them  proper fractions.

1/5 • 2/3 = 2/15

Numerator multiplication: 1 • 2 = 2

Denominator multiplication: 5 • 3 = 15

Multiplying Mixed Fractions

One and one half apples.

One and one half apples is

1 1/2 as a mixed fraction.

Solving mixed fraction math problems:

2 4/6 • 1 3/4 =

  1. Convert mixed numbers to improper fractions:
    2 4/6 • 1 3/4 = 16/6 • 7/4 =
  2. Reduce fractions if possible, keeping them improper fractions:
    8/3 • 7/4 =
  3. Multiply numerators by numerators and denominators by denominators: 56/12 =
  4. Simplify fractions answer: 56/12 = 28/6 = 14/3 = 4 2/3

Multiplying multiple fractions:

3 1/2 • 1 3/5 • 2/3 = 7/2 • 8/5 • 2/3 = 112/30 = 56/15 = 3 11/15

Whole, half and quarter oranges.

8 quarters of orange is 2 whole oranges.

Multiplying Fractions and Mixed Numbers

3 • 1 3/5 • 2/3 = 3/1 • 8/5 • 2/3 = 48/15 = 16/5 = 3 1/5

The process is the same as multiplying mixed fractions. The integer 3 is written as an improper fraction by dividing 3 by 1.
