#### Worksheet Overview

This activity is about the multiplication and division of multiples of 10.

Example 1

Work out:

4,500 ÷ 500 =

This has the same answer as:

450 ÷ 50 or 45 ÷ 5

Tip: If they both have the same number of zeros, simply remove the zeros and do the division sum as normal!

Example 2

Work out:

30 x 500

Here's the detailed explanation of what's happening:

This is 3 x 10 x  5 x 100

which is 3 x 5 x 10 x 100

which is 15 x 1,000

Here's the quick and easy way to work it out!

To work out 30 x 500:  remove the zeros, multiply 3 and 5 and then put the zeros back in again!

3 x 5 plus three zeros gives us 15,000

Does that make it easier?
