There are five times as many red coats as green coats in a sale. If there are 162 red and green coats altogether,
- how many red coats are there?
- how many more red coats than green coats?
(a)
Number of green coats = 1 u
Number of red coats
= 5 x 1 u
= 5 u
Total number of coats
= 5 u + 1 u
= 6 u
6 u = 162
1 u = 162 ÷ 6 = 27
Number of red coats
= 5 u
= 5 x 27
= 135
(b)
Number of more red coats than green coats
= 5 u - 1 u
= 4 u
= 4 x 27
= 108
Answer(s): (a) 135; (b) 108
