### 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.
