Charlie, Bryan and Adam have some stickers in the ratio of 4 : 2 : 5.
Charlie and Bryan have a total of 600 stickers.
- How many stickers does Charlie have?
- How many stickers do Charlie and Adam have?
- How many more stickers does Charlie have than Bryan?
(a)
Number of stickers that Charlie has = 4 u
Number of stickers that Bryan has = 2 u
Number of stickers that Adam has = 5 u
Number of stickers Charlie and Bryan have
= 4 u + 2 u
= 6 u
6 u = 600
1 u = 600 ÷ 6 = 100
Number of stickers that Charlie has
= 4 u
= 4 x 100
= 400
(b)
Number of stickers that Charlie and Adam have
= 4 u + 5 u
= 9 u
= 9 x 100
= 900
(c)
Number of more stickers that Charlie has than Bryan
= 4 u - 2 u
= 2 u
= 2 x 100
= 200
Answer(s): (a) 400; (b) 900; (c) 200
