David, Malachy and Paul share some sweets in the ratio 5:4:1. David gets 20 more sweets than Paul. How many sweets does Malachy get?

16

Step-by-step explanation:

ratio is 5:4:1

David: Malachy: Paul

David gets 20 (that is 4 times more than the original ration. so need to multiply everything by 4)

4*4=16

1*4=4

new ration - 20:16:4

So David gets 20

Malachy gets 16

Paul gets 4
