Adam has four times as many as stickers as Charlie.
- Number of stickers that Adam has = _____ u
- 1 u = _____
- Number of stickers that Bryan has = _____
(a)
Change information into units.
Adam has four times as many as stickers as Charlie.
Number of stickers that Charlie has = 1 u
Number of stickers that Adam has = 4 u
(b)
Bryan + 1 u = 33 --- (1)
Bryan + 4 u = 48 --- (2)
(2) - (1)
4 u - 1 u = 48 - 33
3 u = 15
1 u = 15 ÷ 3 = 5
(c)
Number of stickers that Bryan has
= 33 - 1 u
= 33 - 5
= 28
Answer(s): (a) 4; (b) 5; (c) 28
