- Number of stickers that Charlie has = _____
(a)
Change information into units.
Bryan has five times as many as stickers as Adam.
Number of stickers that Adam has = 1 u
Number of stickers that Bryan has = 5 u
(b)
Charlie + 1 u = 18 --- (1)
Charlie + 5 u = 46 --- (2)
(2) - (1)
5 u - 1 u = 46 - 18
4 u = 28
1 u = 28 ÷ 4 = 7
(c)
Number of stickers that Charlie has
= 18 - 1 u
= 18 - 7
= 11
Answer(s): (a) 5; (b) 7; (c) 11
