Adam and Bryan have some stickers.
23 of Adam's stickers is 54 less than
35 of Bryan's stickers.
Bryan has 260 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 - 54
69 of Adam's stickers =
610 of Bryan's stickers - 54
Let
110 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 10 u
10 u = 260
1 u = 260 ÷ 10 = 26
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 26 - 81
= 234 - 81
= 153
(b)
Number of stickers that Adam and Bryan have altogether
= 9 u - 81 + 10 u
= 153 + 10 x 26
= 153 + 260
= 413
(c)
Number of stickers that Bryan have more than Adam
= 260 - 153
= 107
Answer(s): (a) 153; (b) 413; (c) 107
