This activity is about the multiplication and division of multiples of 10.
Example 1
Work out:
4,500 ÷ 500 =
Answer
This has the same answer as:
450 ÷ 50 or 45 ÷ 5
The answer is 9.
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
Answer
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
The answer is 15,000
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?
