Bryan, Charlie and Adam have some stickers in the ratio of 4 : 3 : 7.
Bryan and Charlie have a total of 700 stickers.
- How many stickers does Bryan have?
- How many stickers do Bryan and Adam have?
- How many more stickers does Bryan have than Charlie?
(a)
Number of stickers that Bryan has = 4 u
Number of stickers that Charlie has = 3 u
Number of stickers that Adam has = 7 u
Number of stickers Bryan and Charlie have
= 4 u + 3 u
= 7 u
7 u = 700
1 u = 700 ÷ 7 = 100
Number of stickers that Bryan has
= 4 u
= 4 x 100
= 400
(b)
Number of stickers that Bryan and Adam have
= 4 u + 7 u
= 11 u
= 11 x 100
= 1100
(c)
Number of more stickers that Bryan has than Charlie
= 4 u - 3 u
= 1 u
= 1 x 100
= 100
Answer(s): (a) 400; (b) 1100; (c) 100
