MEAP Preparation - Grade 4 Mathematics1.73 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 Ũ 5 = 55 can be written as division fact as 55 ũ 5 = 11 or 55 ũ 11 = 5 Directions: Answer the following questions. Also write at least ten examples for multiplication and division as inverse operations.
 Q 1: 15 x 10 = 150. What is the inverse operation?150 ũ 10 = 15150 ũ 15 = 10both Q 2: 6 x 11 = 66. What is the inverse operation?6 ũ 66 = 1166 ũ 6 = 1111 x 6 = 66 Q 3: 5 x 8 = 40. What is the inverse operation?40 ũ 5 = 440 ũ 5 = 88 x 5 = 40 Q 4: 54 ũ 9 = 6. What is the inverse operation?9 x 6 = 5454 ũ 6 = 954 x 9 = 6 Q 5: 48 ũ 6 = 8. What is the inverse operation?8 x 8 = 648 x 6 = 486 x 6 = 36 Q 6: 7 x 8 = 56. What is the inverse operation?8 ũ 7 = 156 ũ 7 = 856 ũ 7 = 5 Q 7: 49 ũ 7 = 7. What is the inverse operation?7 ũ 7 = 4949 ũ 8 = 77 x 7 = 49 Q 8: 35 ũ 7 = 5. What is the inverse operation?35 ũ 5 = 77 x 5 = 357 ũ 35 = 5 Question 9: This question is available to subscribers only!
