- 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 = 12 --- (1)
Bryan + 6 u = 37 --- (2)
(2) - (1)
6 u - 1 u = 37 - 12
5 u = 25
1 u = 25 ÷ 5 = 5
(c)
Number of stickers that Bryan has
= 12 - 1 u
= 12 - 5
= 7
Answer(s): (a) 6; (b) 5; (c) 7
