Answer:
Divide Whole Numbers
We said that addition and subtraction are inverse operations because one undoes the other. Similarly, division is the inverse operation of multiplication. We know \(12 ÷ 4 = 3\) because \(3 • 4 = 12\). Knowing all the multiplication number facts is very important when doing division.

We know \(12 ÷ 4 = 3\) because \(3 • 4 = 12\). Knowing all the multiplication number facts is very important when doing division.We check our answer to division by multiplying the quotient by the divisor to determine if it equals the dividend. In Example \(\PageIndex{2}\), we know \(24 ÷ 8 = 3\) is correct because \(3 • 8 = 24\).
Divide. Then check by multiplying.
Divide. Then check by multiplying.\(42 ÷ 6\)\(\dfrac{72}{9}\)\(7 \overline{\smash{)}63}\)
Divide. Then check by multiplying.\(42 ÷ 6\)\(\dfrac{72}{9}\)\(7 \overline{\smash{)}63}\)Solution
Divide. Then check by multiplying.\(42 ÷ 6\)\(\dfrac{72}{9}\)\(7 \overline{\smash{)}63}\)SolutionDivide 42 by 6.42 ÷ 6 = 7Check by multiplying.7 • 6 = 42 ✓Divide 72 by 9.\(\dfrac{72}{9}\)Check by multiplying.8 • 9 = 72 ✓Divide 63 by 7.\(7 \overline{\smash{)}63}\)Check by multiplying.9 • 7 = 63✓
