Adam and Bryan have some stickers.
34 of Adam's stickers is 30 less than
25 of Bryan's stickers.
Bryan has 285 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.
3x24x2 of Adam's stickers =
2x35x3 of Bryan's stickers - 30
68 of Adam's stickers =
615 of Bryan's stickers - 30
Let
115 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 15 u
15 u = 285
1 u = 285 ÷ 15 = 19
68 of Adam's stickers = 6 u - 30
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 19 - 40
= 152 - 40
= 112
(b)
Number of stickers that Adam and Bryan have altogether
= 112 + 285
= 397
(c)
Number of stickers that Bryan have more than Adam
= 285 - 112
= 173
Answer(s): (a) 112; (b) 397; (c) 173
