- Number of stickers that Charlie has = _____
(a)
Change information into units.
Adam has four times as many as stickers as Bryan.
Number of stickers that Bryan has = 1 u
Number of stickers that Adam has = 4 u
(b)
Charlie + 1 u = 19 --- (1)
Charlie + 4 u = 43 --- (2)
(2) - (1)
4 u - 1 u = 43 - 19
3 u = 24
1 u = 24 ÷ 3 = 8
(c)
Number of stickers that Charlie has
= 19 - 1 u
= 19 - 8
= 11
Answer(s): (a) 4; (b) 8; (c) 11
