Welcome to our How do you Multiply Fractions support page.

This page will support you in learning how to multiply two fractions together, and show you some worked examples.

We have a calculator to help you to multiply fractions.

You can use the calculator for multiplying improper fractions or mixed numbers too.

All the working out is shown step-by-step so you can see how it is worked out.

Before your child tackles multiplying fractions, they should be confident with converting mixed fractions to improper fractions and reducing fractions to simplest form.

Using these sheets will help your child to:

- multiply one fraction by another;
- apply their understanding of simplest form;
- convert an improper fraction to a mixed number.

Frazer says "To multiply a fraction by another fraction, follow these simple steps."

Before you start:

- Convert any mixed numbers into improper fractions;
- Put any integers over a denominator of 1.

Step 1

Multiply the numerators and denominators of the two fractions together. This will give you the answer.

Step 2

Simplify the answer if needed.

You should have now found your fraction of a number!

Example 1) Calculate \[{3 \over 5} \times {4 \over 9} \]

Step 1)

\[{3 \over 5} \times {4 \over 9} = {3 \times 4 \over 5 \times 9} = {12 \over 45}\]

Step 2)

Simplify the answer by dividing numerator and denominator by 3: \[{12 \over 45} \; = \; {4 \over 15}\]

Final answer: \[{3 \over 5} \times {4 \over 9} \; = \; {4 \over 15}\]

Example 2) Calculate \[{2 \over 5} \times {5 \over 8} \]

Step 1)

\[{2 \over 5} \times {5 \over 8} = {2 \times 5 \over 5 \times 8} = {10 \over 40}\]

Step 3)

Simplify the answer by dividing numerator and denominator by 10: \[{10 \over 40} \; = \; {1 \over 4}\]

Final answer: \[{2 \over 5} \times {5 \over 8} \; = \; {1 \over 4}\]

Example 3) Calculate \[{7 \over 4} \times {8 \over 5} \]

Step 1)

\[{7 \over 4} \times {8 \over 5} = {7 \times 8 \over 4 \times 5} = {56 \over 20}\]

Step 3)

Simplify the answer by dividing numerator and denominator by 4: \[{56 \over 20} \; = \; {14 \over 5} \; or \; 2 {4 \over 5}\]

Final answer: \[{7 \over 4} \times {8 \over 5} \; = \; {14 \over 5} \; or \; 2 {4 \over 5}\]

Example 4) Calculate \[{11 \over 7} \times 8 \]

First we need to put the integer over a denominator of 1. \[8 = {8 \over 1} \]

Step 1)

\[{11 \over 7} \times {8 \over 1} = {11 \times 8 \over 7 \times 1} = {88 \over 7}\]

Step 3)

This fraction is already in its simplest form, but we can convert it into a mixed number: \[{88 \over 7} \; = \; 12 {4 \over 7} \]

Final answer: \[{11 \over 7} \times 8 \; = \; {88 \over 7} \; or \; 12 {4 \over 7} \]

Multiplying mixed fractions is very similar to multiplying fractions.

We also have a series of worksheets to help you practice multiplying fractions or multiplying mixed fractions.

The sheets are all carefully graded and the easiest sheets are supported.

This is also sometimes called reducing fractions to their simplest form.

This involves dividing both the numerator and denominator by a common factor to reduce the fraction to the equivalent fraction with the smallest possible numerator and denominator.

This support page shows how to convert improper fractions to mixed numbers, and how to convert mixed numbers to improper fractions.

You will also find printable support sheets, and several practice math worksheets for this learning fractions skill.

Here you will find the Math Salamanders free online Math help pages about Fractions.

There is a wide range of help pages including help with:

- fraction definitions;
