Adam and Bryan have some stickers.
23 of Adam's stickers is 18 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 - 18
69 of Adam's stickers =
616 of Bryan's stickers - 18
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 - 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 11 - 27
= 99 - 27
= 72
(b)
Number of stickers that Adam and Bryan have altogether
= 9 u - 27 + 16 u
= 72 + 16 x 11
= 72 + 176
= 248
(c)
Number of stickers that Bryan have more than Adam
= 176 - 72
= 104
Answer(s): (a) 72; (b) 248; (c) 104
