- Number of stickers that Adam has = _____
(a)
Change information into units.
Bryan has five times as many as stickers as Charlie.
Number of stickers that Charlie has = 1 u
Number of stickers that Bryan has = 5 u
(b)
Adam + 1 u = 23 --- (1)
Adam + 5 u = 39 --- (2)
(2) - (1)
5 u - 1 u = 39 - 23
4 u = 16
1 u = 16 ÷ 4 = 4
(c)
Number of stickers that Adam has
= 23 - 1 u
= 23 - 4
= 19
Answer(s): (a) 5; (b) 4; (c) 19
