Adam and Bryan have some stickers.
34 of Adam's stickers is 15 more than
17 of Bryan's stickers.
Bryan has 210 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.
3 x 14 x 1 of Adam's stickers =
1 x 37 x 3 of Bryan's stickers + 15
34 of Adam's stickers =
321 of Bryan's stickers + 15
Let
121 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 21 u
21 u = 210
1 u = 210 ÷ 21 = 10
34 of Adam's stickers = 3 u + 15
14 of Adam's stickers = 1 u + 5
44 of Adam's stickers = 4 u + 20
Number of stickers that Adam has
= 4 u + 20
= 4 x 10 + 20
= 40 + 20
= 60
(b)
Number of stickers that Adam and Bryan have altogether
= 60 + 210
= 270
(c)
Number of stickers that Bryan has more than Adam
= 210 - 60
= 150
Answer(s): (a) 60; (b) 270; (c) 150
