Adam, Bryan and Charlie have some stickers in the ratio of 8 : 2 : 9.
Adam and Bryan have a total of 600 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 = 8 u
Number of stickers that Bryan has = 2 u
Number of stickers that Charlie has = 9 u
Number of stickers Adam and Bryan have
= 8 u + 2 u
= 10 u
10 u = 600
1 u = 600 ÷ 10 = 60
Number of stickers that Adam has
= 8 u
= 8 x 60
= 480
(b)
Number of stickers that Adam and Charlie have
= 8 u + 9 u
= 17 u
= 17 x 60
= 1020
(c)
Number of less stickers that Bryan has than Adam
= 8 u - 2 u
= 6 u
= 6 x 60
= 360
Answer(s): (a) 480; (b) 1020; (c) 360
