Adam and Bryan have some stickers.
23 of Adam's stickers is 54 less than
37 of Bryan's stickers.
Bryan has 168 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 =
3x27x2 of Bryan's stickers - 54
69 of Adam's stickers =
614 of Bryan's stickers - 54
Let
114 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 14 u
14 u = 168
1 u = 168 ÷ 14 = 12
69 of Adam's stickers = 6 u - 54
19 of Adam's stickers = 1 u - 9
99 of Adam's stickers = 9 u - 81
Number of stickers that Adam has
= 9 u - 81
= 9 x 12 - 81
= 108 - 81
= 27
(b)
Number of stickers that Adam and Bryan have altogether
= 9 u - 81 + 14 u
= 27 + 14 x 12
= 27 + 168
= 195
(c)
Number of stickers that Bryan have more than Adam
= 168 - 27
= 141
Answer(s): (a) 27; (b) 195; (c) 141
