Complete the fact family.
3 × 7 = 21 ___________.
21 ÷ 3 = 7 ___________.
- 7 × 3 = 21, 21 ÷ 7 = 3
- 7 × 7 = 49, 21 ÷ 7 = 4
- 3 × 3 = 9, 21 ÷ 3 = 7
- 3 × 7 = 21, 21 ÷ 21 = 1
The correct answer is: 7 × 3 = 21, 21 ÷ 7 = 3
Fact family
3 × 7 = 21; 7 × 3 = 21
21÷ 3 = 7; 21 ÷ 7 = 3
A fact family in math is defined as a relationship which holds true between the same numbers given. These can be established by using mathematical operations.
