There are six times as many blue skirts as green skirts in a sale. If there are 147 blue and green skirts altogether,
- how many blue skirts are there?
- how many more blue skirts than green skirts?
(a)
Number of green skirts = 1 u
Number of blue skirts
= 6 x 1 u
= 6 u
Total number of skirts
= 6 u + 1 u
= 7 u
7 u = 147
1 u = 147 ÷ 7 = 21
Number of blue skirts
= 6 u
= 6 x 21
= 126
(b)
Number of more blue skirts than green skirts
= 6 u - 1 u
= 5 u
= 5 x 21
= 105
Answer(s): (a) 126; (b) 105
