Adam and Bryan have some stickers.
56 of Adam's stickers is 20 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 16 x 1 of Adam's stickers =
1 x 58 x 5 of Bryan's stickers + 20
56 of Adam's stickers =
540 of Bryan's stickers + 20
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
56 of Adam's stickers = 5 u + 20
16 of Adam's stickers = 1 u + 4
66 of Adam's stickers = 6 u + 24
Number of stickers that Adam has
= 6 u + 24
= 6 x 4 + 24
= 24 + 24
= 48
(b)
Number of stickers that Adam and Bryan have altogether
= 48 + 160
= 208
(c)
Number of stickers that Bryan has more than Adam
= 160 - 48
= 112
Answer(s): (a) 48; (b) 208; (c) 112
