Adam and Bryan have some stickers.
45 of Adam's stickers is 28 more than
23 of Bryan's stickers.
Bryan has 390 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.
4 x 15 x 1 of Adam's stickers =
2 x 23 x 2 of Bryan's stickers + 28
45 of Adam's stickers =
46 of Bryan's stickers + 28
Let
16 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 6 u
6 u = 390
1 u = 390 ÷ 6 = 65
45 of Adam's stickers = 4 u + 28
15 of Adam's stickers = 1 u + 7
55 of Adam's stickers = 5 u + 35
Number of stickers that Adam has
= 5 u + 35
= 5 x 65 + 35
= 325 + 35
= 360
(b)
Number of stickers that Adam and Bryan have altogether
= 360 + 390
= 750
(c)
Number of stickers that Bryan has more than Adam
= 390 - 360
= 30
Answer(s): (a) 360; (b) 750; (c) 30
