There are five times as many red skirts as brown skirts in a sale. If there are 126 red and brown skirts altogether,
- how many red skirts are there?
- how many more red skirts than brown skirts?
(a)
Number of brown skirts = 1 u
Number of red skirts
= 5 x 1 u
= 5 u
Total number of skirts
= 5 u + 1 u
= 6 u
6 u = 126
1 u = 126 ÷ 6 = 21
Number of red skirts
= 5 u
= 5 x 21
= 105
(b)
Number of more red skirts than brown skirts
= 5 u - 1 u
= 4 u
= 4 x 21
= 84
Answer(s): (a) 105; (b) 84
