- Number of stickers that Charlie has = _____
(a)
Change information into units.
Adam has five times as many as stickers as Bryan.
Number of stickers that Bryan has = 1 u
Number of stickers that Adam has = 5 u
(b)
Charlie + 1 u = 9 --- (1)
Charlie + 5 u = 37 --- (2)
(2) - (1)
5 u - 1 u = 37 - 9
4 u = 28
1 u = 28 ÷ 4 = 7
(c)
Number of stickers that Charlie has
= 9 - 1 u
= 9 - 7
= 2
Answer(s): (a) 5; (b) 7; (c) 2
