Answer:
2
Step-by-step explanation:
The larger triangle is 1.5 times larger than the smaller one. So the smaller one has to have a height of 3/1.5=2.
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.
From what we know, p is 20 more than q. So, we can assume p = 20 + q. Q can also be found by subtracting 20 from both sides. So, q = p - 20.
Hope this helped!
