Adam and Bryan have some stickers.
23 of Adam's stickers is 18 less than
35 of Bryan's stickers.
Bryan has 170 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.
2x33x3 of Adam's stickers =
3x25x2 of Bryan's stickers - 18
69 of Adam's stickers =
610 of Bryan's stickers - 18
Let
110 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 10 u
10 u = 170
1 u = 170 ÷ 10 = 17
69 of Adam's stickers = 6 u - 18
19 of Adam's stickers = 1 u - 3
99 of Adam's stickers = 9 u - 27
Number of stickers that Adam has
= 9 u - 27
= 9 x 17 - 27
= 153 - 27
= 126
(b)
Number of stickers that Adam and Bryan have altogether
= 9 u - 27 + 10 u
= 126 + 10 x 17
= 126 + 170
= 296
(c)
Number of stickers that Bryan have more than Adam
= 170 - 126
= 44
Answer(s): (a) 126; (b) 296; (c) 44
