Bryan and Adam have some stickers.
34 of Bryan's stickers is 42 less than
25 of Adam's stickers.
Adam has 285 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 - 42
68 of Bryan's stickers =
615 of Adam's stickers - 42
Let
115 of Adam's stickers be 1 u.
Number of stickers that Adam has = 15 u
15 u = 285
1 u = 285 ÷ 15 = 19
68 of Bryan's stickers = 6 u - 42
18 of Bryan's stickers = 1 u - 7
88 of Bryan's stickers = 8 u - 56
Number of stickers that Bryan has
= 8 u - 56
= 8 x 19 - 56
= 152 - 56
= 96
(b)
Number of stickers that Bryan and Adam have altogether
= 96 + 285
= 381
(c)
Number of stickers that Adam have more than Bryan
= 285 - 96
= 189
Answer(s): (a) 96; (b) 381; (c) 189
