(a)
Change information into units.
Charlie has five times as many as stickers as Bryan.
Number of stickers that Bryan has = 1 u
Number of stickers that Charlie has = 5 u
(b)
Adam + 1 u = 18 --- (1)
Adam + 5 u = 26 --- (2)
(2) - (1)
5 u - 1 u = 26 - 18
4 u = 8
1 u = 8 ÷ 4 = 2
(c)
Number of stickers that Adam has
= 18 - 1 u
= 18 - 2
= 16
Answer(s): (a) 5; (b) 2; (c) 16
