Bryan and Adam have 47 stickers.
Adam has six times as many as stickers as Charlie.
- Number of stickers that Adam has = _____ u
- 1 u = _____
- Number of stickers that Bryan has = _____
(a)
Change information into units.
Adam has six times as many as stickers as Charlie.
Number of stickers that Charlie has = 1 u
Number of stickers that Adam has = 6 u
(b)
Bryan + 1 u = 27 --- (1)
Bryan + 6 u = 47 --- (2)
(2) - (1)
6 u - 1 u = 47 - 27
5 u = 20
1 u = 20 ÷ 5 = 4
(c)
Number of stickers that Bryan has
= 27 - 1 u
= 27 - 4
= 23
Answer(s): (a) 6; (b) 4; (c) 23
