Charlie and Bryan have 40 stickers.
Bryan has six times 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 six times as many as stickers as Adam.
Number of stickers that Adam has = 1 u
Number of stickers that Bryan has = 6 u
(b)
Charlie + 1 u = 25 --- (1)
Charlie + 6 u = 40 --- (2)
(2) - (1)
6 u - 1 u = 40 - 25
5 u = 15
1 u = 15 ÷ 5 = 3
(c)
Number of stickers that Charlie has
= 25 - 1 u
= 25 - 3
= 22
Answer(s): (a) 6; (b) 3; (c) 22
