Check the division with the inverse multiplication fact
Exact division can be verified by reversing the operation. If 120 ÷ 8 = 15, then multiplying the quotient by the divisor must return the original dividend 120.
- 1.Start with the quotient 15.
- 2.15 × 8 = 120.
- 3.The product returns to 120, confirming the division.
