Adam and Bryan have some stickers.
34 of Adam's stickers is 12 less than
25 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.
3x24x2 of Adam's stickers =
2x35x3 of Bryan's stickers - 12
68 of Adam's stickers =
615 of Bryan's stickers - 12
Let
115 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 15 u
15 u = 270
1 u = 270 ÷ 15 = 18
68 of Adam's stickers = 6 u - 12
18 of Adam's stickers = 1 u - 2
88 of Adam's stickers = 8 u - 16
Number of stickers that Adam has
= 8 u - 16
= 8 x 18 - 16
= 144 - 16
= 128
(b)
Number of stickers that Adam and Bryan have altogether
= 128 + 270
= 398
(c)
Number of stickers that Bryan have more than Adam
= 270 - 128
= 142
Answer(s): (a) 128; (b) 398; (c) 142
