Division Fact Families
Multiplication and division are connected. One fact can help you find and check another.
Connected equations
The 3, 4, and 12 fact family
These four equations describe the same relationship between 3, 4, and 12.
3 × 4 = 12
4 × 3 = 12
12 ÷ 3 = 4
12 ÷ 4 = 3
Check with multiplication
Is 20 ÷ 5 = 4 correct?
- 1. Start with the division equation: 20 ÷ 5 = 4.
- 2. Multiply the answer by the divisor: 4 × 5.
- 3. Because 4 × 5 = 20, the division equation is correct.
