Adam and Bryan have some stickers.
47 of Adam's stickers is 20 more than
25 of Bryan's stickers.
Bryan has 290 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 17 x 1 of Adam's stickers =
2 x 25 x 2 of Bryan's stickers + 20
47 of Adam's stickers =
410 of Bryan's stickers + 20
Let
110 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 10 u
10 u = 290
1 u = 290 ÷ 10 = 29
47 of Adam's stickers = 4 u + 20
17 of Adam's stickers = 1 u + 5
77 of Adam's stickers = 7 u + 35
Number of stickers that Adam has
= 7 u + 35
= 7 x 29 + 35
= 203 + 35
= 238
(b)
Number of stickers that Adam and Bryan have altogether
= 238 + 290
= 528
(c)
Number of stickers that Bryan has more than Adam
= 290 - 238
= 52
Answer(s): (a) 238; (b) 528; (c) 52
