Charlie and Adam have 48 stickers.
Adam has thrice as many as stickers as Bryan.
- Number of stickers that Adam has = _____ u
- 1 u = _____
- Number of stickers that Charlie has = _____
(a)
Change information into units.
Adam has thrice as many as stickers as Bryan.
Number of stickers that Bryan has = 1 u
Number of stickers that Adam has = 3 u
(b)
Charlie + 1 u = 24 --- (1)
Charlie + 3 u = 48 --- (2)
(2) - (1)
3 u - 1 u = 48 - 24
2 u = 24
1 u = 24 ÷ 2 = 12
(c)
Number of stickers that Charlie has
= 24 - 1 u
= 24 - 12
= 12
Answer(s): (a) 3; (b) 12; (c) 12
