Grade 3 - Mathematics
2.9 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: 36 6 = 6. What is the inverse operation?
7 x 6 = 42
6 x 6 = 36
6 x 7 = 42

Q 2: 54 9 = 6. What is the inverse operation?
54 x 9 = 6
54 6 = 9
9 x 6 = 54

Q 3: 6 x 11 = 66. What is the inverse operation?
66 6 = 11
6 66 = 11
11 x 6 = 66

Q 4: 15 x 10 = 150. What is the inverse operation?
150 15 = 10
both
150 10 = 15

Q 5: 4 x 5 = 20. What is the inverse operation?
5 4 = 20
20 10 = 2
20 5 = 4

Q 6: 35 7 = 5. What is the inverse operation?
35 5 = 7
7 35 = 5
7 x 5 = 35

Q 7: 48 6 = 8. What is the inverse operation?
6 x 6 = 36
8 x 6 = 48
8 x 8 = 64

Q 8: 7 x 8 = 56. What is the inverse operation?
8 7 = 1
56 7 = 5
56 7 = 8
