Bryan and Charlie have 38 stickers.
Charlie has six times as many as stickers as Adam.
- Number of stickers that Charlie has = _____ u
- 1 u = _____
- Number of stickers that Bryan has = _____
(a)
Change information into units.
Charlie has six times as many as stickers as Adam.
Number of stickers that Adam has = 1 u
Number of stickers that Charlie has = 6 u
(b)
Bryan + 1 u = 23 --- (1)
Bryan + 6 u = 38 --- (2)
(2) - (1)
6 u - 1 u = 38 - 23
5 u = 15
1 u = 15 ÷ 5 = 3
(c)
Number of stickers that Bryan has
= 23 - 1 u
= 23 - 3
= 20
Answer(s): (a) 6; (b) 3; (c) 20
