Welcome to our Fraction of a Whole Number support page. On this page we can help you learn to find a fraction of a number with clear step-by-step instructions and some worked examples.

We also have lots of practice sheets with different levels of support for you to try.

Here you will find some simple information and advice about Fraction of a Whole Number.

At the bottom of this page you will also find two printable resource sheets which explain about how to calculate fractions in a little more detail.

Before you start learning to calculate fractions of numbers, you should be able to work out fractions of shapes.

Here are the two easy steps for finding the fraction of a number:

Step 1 - Find the unit fraction by dividing the number by the denominator

Step 2 - Multiply by the numerator.

You should have now found your fraction of a number!

PLEASE NOTE:

Finding a fraction of a whole number is the same as multiplying the fraction by the whole number.

In other words:

\[ {4 \over 5} \; of \; 30 \; is \; the \; same \; as \; {4 \over 5} \times 30 \]

Step 1)

A unit fraction is a fraction where the numerator is equal to 1.

To find the unit fraction of a number, you need to divide the number by the denominator.

This gives us: \[ {1 \over 6} \; of \; 24 \; = \; 24 ÷ 6 \; = \; 4 \]

Step 2)

To find five-sixths, we need to multiply our answer by the numerator which is 5.

So \[ {5 \over 6} \; of \; 24 = ({1 \over 6} \; of \; 24) \times 5 = 4 \times 5 = 20 \]

Step 1)

To find the unit fraction, we need to divide the number by the denominator.

This gives us: \[ {1 \over 7} \; of \; 35 \; = \; 35 ÷ 7 \; = \; 5 \]

Step 2)

To find three-sevenths, we need to multiply our answer by the numerator which is 3.

So \[ {3 \over 7} \; of \; 35 = ({1 \over 7} \; of \; 35) \times 3 = 5 \times 3 = 15 \]

Step 1)

To find the unit fraction, we need to divide the number by the denominator.

This gives us: \[ {1 \over 10} \; of \; $230 = $230 ÷ 10 = $23 \]

Step 2)

To find three-tenths, we need to multiply our answer by the numerator which is 3.

So \[ {3 \over 10} \; of \; $230 = ({1 \over 10} \; of \; $230) \times 3 \] and \[ ({1 \over 10} \; of \; $230) \times 3 = $23 \times 3 = $69 \]

Final answer \[ {3 \over 10} \; of \; $230 \; = \; $69 \]

For those of you who like to see things in Algebra...this is what it looks like

If we want to work out: \[ {a \over b} \; of \; a \; number \; n \]

First we work out: \[ {1 \over b} \; of \; n = {n \over b} \; \; or \; n ÷ b \]

Next we need to multiply this by the numerator a.

This gives us: \[ {a \over b} \; of \; n = {n \over b} \times a = {na \over b} \; \; or \; na ÷ b \]

This printable support sheet below gives a little more detail about finding fractions of numbers including a step-by-step visual guide to how and why it works.

These problems all involve finding the fraction of a whole number.

There are 3 versions of each sheet:

- Sheets 1a and 2a are the easiest. They mainly involve finding simple unit fractions of small numbers.
- Sheets 1b and 2b are a little harder. They involve finding (mainly unit) fractions of larger numbers.
- Sheets 1c and 2c are hardest. They involve finding non-unit fractions of larger numbers.
