Charlie, Adam and Bryan have some stickers in the ratio of 8 : 2 : 5.
Charlie and Adam have a total of 900 stickers.
- How many stickers does Charlie have?
- How many stickers do Charlie and Bryan have?
- How many more stickers does Charlie have than Adam?
(a)
Number of stickers that Charlie has = 8 u
Number of stickers that Adam has = 2 u
Number of stickers that Bryan has = 5 u
Number of stickers Charlie and Adam have
= 8 u + 2 u
= 10 u
10 u = 900
1 u = 900 ÷ 10 = 90
Number of stickers that Charlie has
= 8 u
= 8 x 90
= 720
(b)
Number of stickers that Charlie and Bryan have
= 8 u + 5 u
= 13 u
= 13 x 90
= 1170
(c)
Number of more stickers that Charlie has than Adam
= 8 u - 2 u
= 6 u
= 6 x 90
= 540
Answer(s): (a) 720; (b) 1170; (c) 540
