Adam, Bryan and Charlie have some stickers in the ratio of 9 : 7 : 7.
Adam and Bryan have a total of 800 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 = 9 u
Number of stickers that Bryan has = 7 u
Number of stickers that Charlie has = 7 u
Number of stickers Adam and Bryan have
= 9 u + 7 u
= 16 u
16 u = 800
1 u = 800 ÷ 16 = 50
Number of stickers that Adam has
= 9 u
= 9 x 50
= 450
(b)
Number of stickers that Adam and Charlie have
= 9 u + 7 u
= 16 u
= 16 x 50
= 800
(c)
Number of less stickers that Bryan has than Adam
= 9 u - 7 u
= 2 u
= 2 x 50
= 100
Answer(s): (a) 450; (b) 800; (c) 100
