(a)
Change information into units.
Charlie has six times as many as stickers as Bryan.
Number of stickers that Bryan has = 1 u
Number of stickers that Charlie has = 6 u
(b)
Adam + 1 u = 12 --- (1)
Adam + 6 u = 47 --- (2)
(2) - (1)
6 u - 1 u = 47 - 12
5 u = 35
1 u = 35 ÷ 5 = 7
(c)
Number of stickers that Adam has
= 12 - 1 u
= 12 - 7
= 5
Answer(s): (a) 6; (b) 7; (c) 5
