Adam and Bryan have some stickers.
58 of Adam's stickers is 25 more than
13 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.
5 x 18 x 1 of Adam's stickers =
1 x 53 x 5 of Bryan's stickers + 25
58 of Adam's stickers =
515 of Bryan's stickers + 25
Let
115 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 15 u
15 u = 390
1 u = 390 ÷ 15 = 26
58 of Adam's stickers = 5 u + 25
18 of Adam's stickers = 1 u + 5
88 of Adam's stickers = 8 u + 40
Number of stickers that Adam has
= 8 u + 40
= 8 x 26 + 40
= 208 + 40
= 248
(b)
Number of stickers that Adam and Bryan have altogether
= 248 + 390
= 638
(c)
Number of stickers that Bryan has more than Adam
= 390 - 248
= 142
Answer(s): (a) 248; (b) 638; (c) 142
