Adam and Bryan have some stickers.
34 of Adam's stickers is 72 less than
25 of Bryan's stickers.
Bryan has 255 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 - 72
68 of Adam's stickers =
615 of Bryan's stickers - 72
Let
115 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 15 u
15 u = 255
1 u = 255 ÷ 15 = 17
68 of Adam's stickers = 6 u - 72
18 of Adam's stickers = 1 u - 12
88 of Adam's stickers = 8 u - 96
Number of stickers that Adam has
= 8 u - 96
= 8 x 17 - 96
= 136 - 96
= 40
(b)
Number of stickers that Adam and Bryan have altogether
= 40 + 255
= 295
(c)
Number of stickers that Bryan have more than Adam
= 255 - 40
= 215
Answer(s): (a) 40; (b) 295; (c) 215
