Adam and Bryan have some stickers.
57 of Adam's stickers is 45 more than
18 of Bryan's stickers.
Bryan has 160 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 + 45
57 of Adam's stickers =
540 of Bryan's stickers + 45
Let
140 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 40 u
40 u = 160
1 u = 160 ÷ 40 = 4
57 of Adam's stickers = 5 u + 45
17 of Adam's stickers = 1 u + 9
77 of Adam's stickers = 7 u + 63
Number of stickers that Adam has
= 7 u + 63
= 7 x 4 + 63
= 28 + 63
= 91
(b)
Number of stickers that Adam and Bryan have altogether
= 91 + 160
= 251
(c)
Number of stickers that Bryan has more than Adam
= 160 - 91
= 69
Answer(s): (a) 91; (b) 251; (c) 69
