Charlie and Bryan have 24 stickers.
Bryan has thrice as many as stickers as Adam.
- Number of stickers that Bryan has = _____ u
- 1 u = _____
- Number of stickers that Charlie has = _____
(a)
Change information into units.
Bryan has thrice as many as stickers as Adam.
Number of stickers that Adam has = 1 u
Number of stickers that Bryan has = 3 u
(b)
Charlie + 1 u = 10 --- (1)
Charlie + 3 u = 24 --- (2)
(2) - (1)
3 u - 1 u = 24 - 10
2 u = 14
1 u = 14 ÷ 2 = 7
(c)
Number of stickers that Charlie has
= 10 - 1 u
= 10 - 7
= 3
Answer(s): (a) 3; (b) 7; (c) 3
