Adam and Bryan have some stickers.
38 of Adam's stickers is 27 more than
16 of Bryan's stickers.
Bryan has 270 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.
3 x 18 x 1 of Adam's stickers =
1 x 36 x 3 of Bryan's stickers + 27
38 of Adam's stickers =
318 of Bryan's stickers + 27
Let
118 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 18 u
18 u = 270
1 u = 270 ÷ 18 = 15
38 of Adam's stickers = 3 u + 27
18 of Adam's stickers = 1 u + 9
88 of Adam's stickers = 8 u + 72
Number of stickers that Adam has
= 8 u + 72
= 8 x 15 + 72
= 120 + 72
= 192
(b)
Number of stickers that Adam and Bryan have altogether
= 192 + 270
= 462
(c)
Number of stickers that Bryan has more than Adam
= 270 - 192
= 78
Answer(s): (a) 192; (b) 462; (c) 78
