Adam and Bryan have some stickers.
35 of Adam's stickers is 18 more than
25 of Bryan's stickers.
Bryan has 360 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 25 x 2 of Adam's stickers =
2 x 35 x 3 of Bryan's stickers + 18
610 of Adam's stickers =
615 of Bryan's stickers + 18
Let
115 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 15 u
15 u = 360
1 u = 360 ÷ 15 = 24
610 of Adam's stickers = 6 u + 18
110 of Adam's stickers = 1 u + 3
1010 of Adam's stickers = 10 u + 30
Number of stickers that Adam has
= 10 u + 30
= 10 x 24 + 30
= 240 + 30
= 270
(b)
Number of stickers that Adam and Bryan have altogether
= 270 + 360
= 630
(c)
Number of stickers that Bryan has more than Adam
= 360 - 270
= 90
Answer(s): (a) 270; (b) 630; (c) 90
