Adam has 10 less red stickers than green stickers.
Adam has 3 times as many green stickers as red stickers.
- Number of green stickers
- Number of red stickers
- Total number of stickers
- Number of less red stickers than green stickers
(a)
The number of green stickers is 3 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 = 3 u
Number of less red stickers than green stickers = 3 u - 1 u = 2 u
2 u = 10
1 u = 10 ÷ 2 = 5
Number of green stickers
= 3 u
= 3 x 5
= 15
(b)
Number of red stickers
= 1 u
= 5
(c)
Total number of stickers
= 3 u + 1 u
= 4 u
= 4 x 5
= 20
(d)
Number of less red stickers than green stickers
= 3 u - 1 u
= 2 u
= 2 x 5
= 10
Answer(s): (a) 15; (b) 5; (c) 20; (d) 10
