Adam has 90 stickers.
Adam has 2 times as many green stickers as red stickers.
- Number of green stickers = _____
- Number of more green stickers than red stickers = _____
- Total number of stickers = _____
- Number of less red stickers than green stickers = _____
(a)
The number of green stickers is 2 times the number of red stickers.
The number of red stickers is the smaller group.
Number of red stickers = 1 u
Number of green stickers = 2 u
Total number of stickers = 1 u + 2 u = 3 u
3 u = 90
1 u = 90 ÷ 3 = 30
Number of green stickers
= 2 u
= 2 x 30
= 60
(b)
Number of more green stickers than red stickers
= 2 u - 1 u
= 1 u
= 1 x 30
= 30
(c)
Total number of stickers
= 2 u + 1 u
= 3 u
= 3 x 30
= 90
(d)
Number of less red stickers than green stickers
= 2 u - 1 u
= 1 u
= 1 x 30
= 30
Answer(s): (a) 60; (b) 30; (c) 90; (d) 30
