Bryan, Charlie and Adam have some stickers in the ratio of 3 : 2 : 2.
Bryan and Charlie have a total of 600 stickers.
- How many stickers does Bryan have?
- How many stickers do Bryan and Adam have?
- How many more stickers does Bryan have than Charlie?
(a)
Number of stickers that Bryan has = 3 u
Number of stickers that Charlie has = 2 u
Number of stickers that Adam has = 2 u
Number of stickers Bryan and Charlie have
= 3 u + 2 u
= 5 u
5 u = 600
1 u = 600 ÷ 5 = 120
Number of stickers that Bryan has
= 3 u
= 3 x 120
= 360
(b)
Number of stickers that Bryan and Adam have
= 3 u + 2 u
= 5 u
= 5 x 120
= 600
(c)
Number of more stickers that Bryan has than Charlie
= 3 u - 2 u
= 1 u
= 1 x 120
= 120
Answer(s): (a) 360; (b) 600; (c) 120
