Adam has 60 stickers.
Adam has 3 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 3 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 = 3 u
Total number of stickers = 1 u + 3 u = 4 u
4 u = 60
1 u = 60 ÷ 4 = 15
Number of red stickers
= 3 u
= 3 x 15
= 45
(b)
Number of more red stickers than blue stickers
= 3 u - 1 u
= 2 u
= 2 x 15
= 30
(c)
Total number of stickers
= 3 u + 1 u
= 4 u
= 4 x 15
= 60
(d)
Number of less blue stickers than red stickers
= 3 u - 1 u
= 2 u
= 2 x 15
= 30
Answer(s): (a) 45; (b) 30; (c) 60; (d) 30
