Adam has 20 stickers.
Adam has 4 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 4 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 = 4 u
Total number of stickers = 1 u + 4 u = 5 u
5 u = 20
1 u = 20 ÷ 5 = 4
Number of red stickers
= 4 u
= 4 x 4
= 16
(b)
Number of more red stickers than blue stickers
= 4 u - 1 u
= 3 u
= 3 x 4
= 12
(c)
Total number of stickers
= 4 u + 1 u
= 5 u
= 5 x 4
= 20
(d)
Number of less blue stickers than red stickers
= 4 u - 1 u
= 3 u
= 3 x 4
= 12
Answer(s): (a) 16; (b) 12; (c) 20; (d) 12
