Missing Factors

We can use division or multiplication to find missing numbers

We can use a related multiplication fact to divide two numbers. For example, to find 32 ÷ 8, we can use 4 x 8 = 32 as the related multiplication fact

We can use a fact family to divide two numbers

Multiplication and division are inverse operations. One is the opposite of the other

The Commutative Property of Multiplication says that the order of factors does not affect the product. For example: 4 x 6 = 24, and 6 x 4 = 24

Some fact families are:
a) 2 x 4 = 8; 4 x 2 = 8; 8 ÷ 4 = 2; 8 ÷ 2 = 4
b) 3 x 3 = 9; 9 ÷ 3 = 3
c) 9 x 1 = 9; 1 x 9 = 9; 9 ÷ 1 = 9; 9 ÷ 9 = 1
