Adam, Bryan and Charlie have some stickers in the ratio of 4 : 2 : 3.
Adam and Bryan have a total of 300 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 = 4 u
Number of stickers that Bryan has = 2 u
Number of stickers that Charlie has = 3 u
Number of stickers Adam and Bryan have
= 4 u + 2 u
= 6 u
6 u = 300
1 u = 300 ÷ 6 = 50
Number of stickers that Adam has
= 4 u
= 4 x 50
= 200
(b)
Number of stickers that Adam and Charlie have
= 4 u + 3 u
= 7 u
= 7 x 50
= 350
(c)
Number of less stickers that Bryan has than Adam
= 4 u - 2 u
= 2 u
= 2 x 50
= 100
Answer(s): (a) 200; (b) 350; (c) 100
