Introduction
In this activity, we will be using factor pairs to help us divide larger numbers.
To answer the question 600 ÷ 3
We know that 2 × 3 = 6
We also know that 20 x 3 = 60
This means that 200 × 3 = 600
So 600 ÷ 3 = 200
Example 1
Use the factor pair 3 × 4 = 12 to work out 120 ÷ 30
Answer
3 × 4 = 12
30 × 4 = 120
120 ÷ 30 = 4
Example 2
Use the factor pair 5 × 3 = 15 to work out 1,500 ÷ 5
Answer
5 × 3 = 15
5 x 30 = 150
5 × 300 = 1,500
1,500 ÷ 5 = 300
Does that make these calculations easier to do in your head?
