÷2, ÷5, ÷10 worksheet

Part A: Working out and filling in

1. 1. 60 ÷ 5 = 12

   60 ÷ 5: ÷5 is double, then ÷10, 60 × 2 = 120, 120 ÷ 10 = 12

2. 2. 10 ÷ 2 = 5

   10 ÷ 2: ÷2 is halving, 5 + 5 = 10

3. 3. 20 ÷ 10 = 2

   20 ÷ 10: ÷10 takes a zero off → 2

4. 4. 90 ÷ 10 = 9

   90 ÷ 10: ÷10 takes a zero off → 9

5. 5. 4 ÷ 2 = 2

   4 ÷ 2: ÷2 is halving, 2 + 2 = 4

6. 6. 10 ÷ 5 = 2

   10 ÷ 5: ÷5 is double, then ÷10, 10 × 2 = 20, 20 ÷ 10 = 2

7. 7. 6 ÷ 2 = 3

   6 ÷ 2: ÷2 is halving, 3 + 3 = 6

8. 8. 8 ÷ 2 = 4

   8 ÷ 2: ÷2 is halving, 4 + 4 = 8

9. 9. 12 ÷ 2 = 6

   12 ÷ 2: ÷2 is halving, 6 + 6 = 12

10. 10. 55 ÷ 5 = 11

    55 ÷ 5: ÷5 is double, then ÷10, 55 × 2 = 110, 110 ÷ 10 = 11

11. 11. 16 ÷ 2 = 8

    16 ÷ 2: ÷2 is halving, 8 + 8 = 16

12. 12. 20 ÷ 5 = 4

    20 ÷ 5: ÷5 is double, then ÷10, 20 × 2 = 40, 40 ÷ 10 = 4

Part B: Word problems
