Bryan, Adam and Charlie have some stickers in the ratio of 3 : 2 : 8.
Bryan and Adam have a total of 300 stickers.
- How many stickers does Bryan have?
- How many stickers do Bryan and Charlie have?
- How many more stickers does Bryan have than Adam?
(a)
Number of stickers that Bryan has = 3 u
Number of stickers that Adam has = 2 u
Number of stickers that Charlie has = 8 u
Number of stickers Bryan and Adam have
= 3 u + 2 u
= 5 u
5 u = 300
1 u = 300 ÷ 5 = 60
Number of stickers that Bryan has
= 3 u
= 3 x 60
= 180
(b)
Number of stickers that Bryan and Charlie have
= 3 u + 8 u
= 11 u
= 11 x 60
= 660
(c)
Number of more stickers that Bryan has than Adam
= 3 u - 2 u
= 1 u
= 1 x 60
= 60
Answer(s): (a) 180; (b) 660; (c) 60
