Adam and Bryan have some stickers.
57 of Adam's stickers is 50 more than
18 of Bryan's stickers.
Bryan has 200 stickers.
- How many stickers does Adam have?
- How many stickers do Adam and Bryan have altogether?
- How many stickers does Bryan have more than Adam?
(a)
Make the numerators the same.
5 x 17 x 1 of Adam's stickers =
1 x 58 x 5 of Bryan's stickers + 50
57 of Adam's stickers =
540 of Bryan's stickers + 50
Let
140 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 40 u
40 u = 200
1 u = 200 ÷ 40 = 5
57 of Adam's stickers = 5 u + 50
17 of Adam's stickers = 1 u + 10
77 of Adam's stickers = 7 u + 70
Number of stickers that Adam has
= 7 u + 70
= 7 x 5 + 70
= 35 + 70
= 105
(b)
Number of stickers that Adam and Bryan have altogether
= 105 + 200
= 305
(c)
Number of stickers that Bryan has more than Adam
= 200 - 105
= 95
Answer(s): (a) 105; (b) 305; (c) 95
