Charlie, Adam and Bryan have some stickers in the ratio of 4 : 2 : 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 less stickers does Adam have than Charlie?
(a)
Number of stickers that Charlie has = 4 u
Number of stickers that Adam has = 2 u
Number of stickers that Bryan has = 7 u
Number of stickers Charlie and Adam 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 Bryan have
= 4 u + 7 u
= 11 u
= 11 x 100
= 1100
(c)
Number of less stickers that Adam has than Charlie
= 4 u - 2 u
= 2 u
= 2 x 100
= 200
Answer(s): (a) 400; (b) 1100; (c) 200
