Adam has 30 less green stickers than red stickers.
Adam has 4 times as many red stickers as green stickers.
- Number of red stickers
- Number of green stickers
- Total number of stickers
- Number of less green stickers than red stickers
(a)
The number of red stickers is 4 times the number of green stickers.
The number of green stickers is the smaller group.
Number of green stickers = 1 u
Number of red stickers = 4 u
Number of less green stickers than red stickers = 4 u - 1 u = 3 u
3 u = 30
1 u = 30 ÷ 3 = 10
Number of red stickers
= 4 u
= 4 x 10
= 40
(b)
Number of green stickers
= 1 u
= 10
(c)
Total number of stickers
= 4 u + 1 u
= 5 u
= 5 x 10
= 50
(d)
Number of less green stickers than red stickers
= 4 u - 1 u
= 3 u
= 3 x 10
= 30
Answer(s): (a) 40; (b) 10; (c) 50; (d) 30
