Adam has 70 less red stickers than blue stickers.
Adam has 8 times as many blue stickers as red stickers.
- Number of blue stickers
- Number of red stickers
- Total number of stickers
- Number of less red stickers than blue stickers
(a)
The number of blue stickers is 8 times the number of red stickers.
The number of red stickers is the smaller group.
Number of red stickers = 1 u
Number of blue stickers = 8 u
Number of less red stickers than blue stickers = 8 u - 1 u = 7 u
7 u = 70
1 u = 70 ÷ 7 = 10
Number of blue stickers
= 8 u
= 8 x 10
= 80
(b)
Number of red stickers
= 1 u
= 10
(c)
Total number of stickers
= 8 u + 1 u
= 9 u
= 9 x 10
= 90
(d)
Number of less red stickers than blue stickers
= 8 u - 1 u
= 7 u
= 7 x 10
= 70
Answer(s): (a) 80; (b) 10; (c) 90; (d) 70
