Charlie, Adam and Bryan have some stickers in the ratio of 9 : 3 : 7.
Charlie and Adam have a total of 600 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 = 9 u
Number of stickers that Adam has = 3 u
Number of stickers that Bryan has = 7 u
Number of stickers Charlie and Adam have
= 9 u + 3 u
= 12 u
12 u = 600
1 u = 600 ÷ 12 = 50
Number of stickers that Charlie has
= 9 u
= 9 x 50
= 450
(b)
Number of stickers that Charlie and Bryan have
= 9 u + 7 u
= 16 u
= 16 x 50
= 800
(c)
Number of more stickers that Charlie has than Adam
= 9 u - 3 u
= 6 u
= 6 x 50
= 300
Answer(s): (a) 450; (b) 800; (c) 300
