Question

4 balls of wool will make 8 knitted caps. How many balls of wool will Malcolm need if he wants to make 6 caps?

Answer 1

Since 4 balls of wool makes 8 knitted caps we'll find out how much caps each ball makes.

8/4 = 2

Each ball makes 2 caps.

6/2 = 3

Malcolm will need 3 balls of wool to make 6 knitted caps.
