Adam and Bryan have some stickers.
23 of Adam's stickers is 36 less than
38 of Bryan's stickers.
Bryan has 176 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 =
3x28x2 of Bryan's stickers - 36
69 of Adam's stickers =
616 of Bryan's stickers - 36
Let
116 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 16 u
16 u = 176
1 u = 176 ÷ 16 = 11
69 of Adam's stickers = 6 u - 36
19 of Adam's stickers = 1 u - 6
99 of Adam's stickers = 9 u - 54
Number of stickers that Adam has
= 9 u - 54
= 9 x 11 - 54
= 99 - 54
= 45
(b)
Number of stickers that Adam and Bryan have altogether
= 9 u - 54 + 16 u
= 45 + 16 x 11
= 45 + 176
= 221
(c)
Number of stickers that Bryan have more than Adam
= 176 - 45
= 131
Answer(s): (a) 45; (b) 221; (c) 131
