Adam has 20 less blue stickers than red stickers.
Adam has 6 times as many red stickers as blue stickers.
- Number of red stickers
- Number of blue stickers
- Total number of stickers
- Number of less blue stickers than red stickers
(a)
The number of red stickers is 6 times the number of blue stickers.
The number of blue stickers is the smaller group.
Number of blue stickers = 1 u
Number of red stickers = 6 u
Number of less blue stickers than red stickers = 6 u - 1 u = 5 u
5 u = 20
1 u = 20 ÷ 5 = 4
Number of red stickers
= 6 u
= 6 x 4
= 24
(b)
Number of blue stickers
= 1 u
= 4
(c)
Total number of stickers
= 6 u + 1 u
= 7 u
= 7 x 4
= 28
(d)
Number of less blue stickers than red stickers
= 6 u - 1 u
= 5 u
= 5 x 4
= 20
Answer(s): (a) 24; (b) 4; (c) 28; (d) 20
