- Number of stickers that Bryan has = _____
(a)
Change information into units.
Adam has five times as many as stickers as Charlie.
Number of stickers that Charlie has = 1 u
Number of stickers that Adam has = 5 u
(b)
Bryan + 1 u = 8 --- (1)
Bryan + 5 u = 20 --- (2)
(2) - (1)
5 u - 1 u = 20 - 8
4 u = 12
1 u = 12 ÷ 4 = 3
(c)
Number of stickers that Bryan has
= 8 - 1 u
= 8 - 3
= 5
Answer(s): (a) 5; (b) 3; (c) 5
