There are five times as many gold coats as green coats in a sale. If there are 144 gold and green coats altogether,
- how many gold coats are there?
- how many more gold coats than green coats?
(a)
Number of green coats = 1 u
Number of gold coats
= 5 x 1 u
= 5 u
Total number of coats
= 5 u + 1 u
= 6 u
6 u = 144
1 u = 144 ÷ 6 = 24
Number of gold coats
= 5 u
= 5 x 24
= 120
(b)
Number of more gold coats than green coats
= 5 u - 1 u
= 4 u
= 4 x 24
= 96
Answer(s): (a) 120; (b) 96
