Adam, Bryan and Charlie have some stickers in the ratio of 3 : 2 : 2.
Adam and Bryan have a total of 400 stickers.
- How many stickers does Adam have?
- How many stickers do Adam and Charlie have?
- How many more stickers does Adam have than Bryan?
(a)
Number of stickers that Adam has = 3 u
Number of stickers that Bryan has = 2 u
Number of stickers that Charlie has = 2 u
Number of stickers Adam and Bryan have
= 3 u + 2 u
= 5 u
5 u = 400
1 u = 400 ÷ 5 = 80
Number of stickers that Adam has
= 3 u
= 3 x 80
= 240
(b)
Number of stickers that Adam and Charlie have
= 3 u + 2 u
= 5 u
= 5 x 80
= 400
(c)
Number of more stickers that Adam has than Bryan
= 3 u - 2 u
= 1 u
= 1 x 80
= 80
Answer(s): (a) 240; (b) 400; (c) 80
