(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 = 9 --- (1)
Adam + 6 u = 19 --- (2)
(2) - (1)
6 u - 1 u = 19 - 9
5 u = 10
1 u = 10 ÷ 5 = 2
(c)
Number of stickers that Adam has
= 9 - 1 u
= 9 - 2
= 7
Answer(s): (a) 6; (b) 2; (c) 7
