Adam, Bryan and Charlie have some stickers in the ratio of 6 : 4 : 7.
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 more stickers does Adam have than Bryan?
(a)
Number of stickers that Adam has = 6 u
Number of stickers that Bryan has = 4 u
Number of stickers that Charlie has = 7 u
Number of stickers Adam and Bryan have
= 6 u + 4 u
= 10 u
10 u = 900
1 u = 900 ÷ 10 = 90
Number of stickers that Adam has
= 6 u
= 6 x 90
= 540
(b)
Number of stickers that Adam and Charlie have
= 6 u + 7 u
= 13 u
= 13 x 90
= 1170
(c)
Number of more stickers that Adam has than Bryan
= 6 u - 4 u
= 2 u
= 2 x 90
= 180
Answer(s): (a) 540; (b) 1170; (c) 180
