A snail can crawl 30 inches in 5 minutes. If it crawls at this speed
in one direction, how far will it travel in 1 minute?

Division as rEpEatED subtraction

Mahi has 20 laddoos. She wants to divide them equally among 4 children. She starts by
giving one laddoo to each child.

Total laddoos

20 16
Step 1: – 4 Step 2: – 4
16 12

12 8
Step 3: – 4 Step 4: – 4
8
4
4
Step 5: – 4
0

No more laddoos are left for distribution. Thus, each child gets 5 laddoos. Here, we

subtract 4, five times from 20. So, we can say that 20 ÷ 4 = 5.
Thus, division is also called repeated subtraction.
