- Number of stickers that Charlie has = _____
(a)
Change information into units.
Adam has six times as many as stickers as Bryan.
Number of stickers that Bryan has = 1 u
Number of stickers that Adam has = 6 u
(b)
Charlie + 1 u = 10 --- (1)
Charlie + 6 u = 30 --- (2)
(2) - (1)
6 u - 1 u = 30 - 10
5 u = 20
1 u = 20 ÷ 5 = 4
(c)
Number of stickers that Charlie has
= 10 - 1 u
= 10 - 4
= 6
Answer(s): (a) 6; (b) 4; (c) 6
