Adam, Bryan and Charlie have some stickers in the ratio of 3 : 2 : 3.
Adam and Bryan have a total of 900 stickers.
- How many stickers does Adam have?
- How many stickers do Adam and Charlie have?
- How many less stickers does Bryan have than Adam?
(a)
Number of stickers that Adam has = 3 u
Number of stickers that Bryan has = 2 u
Number of stickers that Charlie has = 3 u
Number of stickers Adam and Bryan have
= 3 u + 2 u
= 5 u
5 u = 900
1 u = 900 ÷ 5 = 180
Number of stickers that Adam has
= 3 u
= 3 x 180
= 540
(b)
Number of stickers that Adam and Charlie have
= 3 u + 3 u
= 6 u
= 6 x 180
= 1080
(c)
Number of less stickers that Bryan has than Adam
= 3 u - 2 u
= 1 u
= 1 x 180
= 180
Answer(s): (a) 540; (b) 1080; (c) 180
