- Number of stickers that Adam has = _____
(a)
Change information into units.
Bryan has six times as many as stickers as Charlie.
Number of stickers that Charlie has = 1 u
Number of stickers that Bryan has = 6 u
(b)
Adam + 1 u = 18 --- (1)
Adam + 6 u = 28 --- (2)
(2) - (1)
6 u - 1 u = 28 - 18
5 u = 10
1 u = 10 ÷ 5 = 2
(c)
Number of stickers that Adam has
= 18 - 1 u
= 18 - 2
= 16
Answer(s): (a) 6; (b) 2; (c) 16
