Adam has 60 stickers.
Adam has 2 times as many red stickers as blue stickers.
- Number of red stickers = _____
- Number of more red stickers than blue stickers = _____
- Total number of stickers = _____
- Number of less blue stickers than red stickers = _____
(a)
The number of red stickers is 2 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 = 2 u
Total number of stickers = 1 u + 2 u = 3 u
3 u = 60
1 u = 60 ÷ 3 = 20
Number of red stickers
= 2 u
= 2 x 20
= 40
(b)
Number of more red stickers than blue stickers
= 2 u - 1 u
= 1 u
= 1 x 20
= 20
(c)
Total number of stickers
= 2 u + 1 u
= 3 u
= 3 x 20
= 60
(d)
Number of less blue stickers than red stickers
= 2 u - 1 u
= 1 u
= 1 x 20
= 20
Answer(s): (a) 40; (b) 20; (c) 60; (d) 20
