1. How many division facts can you find for 5 × 5 = 25? _________
2. Complete the table.

Multiplication Facts Corresponding Division Facts

(a) 7 × 6 = 42 42 ÷ 7 = 6

(b) 6 × = 42 42 ÷ 6 =

(c) 6 × 5 = 30 ÷ = 6
(d ) 5 × 6 = ÷ 6 = 5

(e) 10 × 8 = ÷ 8 = 10

(f ) 8 × = 80 80 ÷ 10 =

DIVISION USING mULTIPLICATION TABLES

Using multiplication tables, we can do division sums.

example: Divide the following using multiplication.

(a) 10 ÷ 2 = ? (b) 18 ÷ 3 = ?

Solution: (a) Recall the multiplication (b) Recall the multiplication

table of 2. table of 3.

1 × 2 = 2 1 × 3 = 3

2 × 2 = 4 2 × 3 = 6

3 × 2 = 6 3 × 3 = 9

4 × 2 = 8 4 × 3 = 12

5 × 2 = 10 (stop here) 5 × 3 = 15

Using the relation between 6 × 3 = 18 (stop here)

division and multiplication, Using the relation between

we find that division and multiplication,

10 ÷ 2 = 5. we find that

18 ÷ 3 = 6.
