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