(c) 16 ÷ 2 =

16 – 2 – 2 – 2 – 4 – 4 – 2 – 4 – 2

(d) 25 ÷ 5 =

25 – 5 – 5 – 3 – 5 – 3

(e) 32 ÷ 4 =

32 – 8 – 4 – 8 – 8 – 4 – 4 – 8 – 4

3 Look at the example and divide by repeated subtraction on a number line.

(a) Distribute 21 pencils to a group of 7 friends.

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

Start from 21 . Go back 7 steps 3 times to reach 0.

Thus, 21 ÷ 7 = 3 .

(b) Distribute 18 bananas equally among 6 family members.

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

Start from . Go back steps times to reach 0.

Thus, ÷ = .
