Relate Division to Multiplication
Multiplication and division are closely related. Multiplication combines
equal groups of objects to find a product. Division divides a set of
objects into equal groups.
4 groups of 6
24
24 divided into
4 equal groups
4 × 6 = 24
6 in each group
24 ÷ 4 = 6
The numbers 4, 6, and 24 are part of a fact family. A fact family is a set
of four facts that use the same three numbers.
4 × 6 = 24
6 × 4 = 24
24 ÷ 4 = 6
24 ÷ 6 = 4
