(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 = 15 --- (1)
Charlie + 5 u = 39 --- (2)
(2) - (1)
5 u - 1 u = 39 - 15
4 u = 24
1 u = 24 ÷ 4 = 6
(c)
Number of stickers that Charlie has
= 15 - 1 u
= 15 - 6
= 9
Answer(s): (a) 5; (b) 6; (c) 9
