### Grade 3 - Mathematics2.9 Multiplication and Division as Inverse Operations

 An inverse operation reverses another operation. Addition and subtraction are inverses of each other. Example: The addition fact 9 + 5 = 14 can be written as subtraction fact as 14 - 5 = 9 or 14 - 9 = 5 Similarly, multiplication and division are inverses of each other. Example: The multiplication fact 11 × 5 = 55 can be written as division fact as 55 ÷ 5 = 11 or 55 ÷ 11 = 5 Directions: Answer the following questions. Also write at least ten examples for multiplication and division as inverse operations.
 Q 1: 7 x 8 = 56. What is the inverse operation?56 ÷ 7 = 88 ÷ 7 = 156 ÷ 7 = 5 Q 2: 6 x 11 = 66. What is the inverse operation?6 ÷ 66 = 1111 x 6 = 6666 ÷ 6 = 11 Q 3: 4 x 5 = 20. What is the inverse operation?20 ÷ 5 = 420 ÷ 10 = 25 ÷ 4 = 20 Q 4: 35 ÷ 7 = 5. What is the inverse operation?35 ÷ 5 = 77 ÷ 35 = 57 x 5 = 35 Question 5: This question is available to subscribers only!
