Bryan and Adam have some stickers.
57 of Bryan's stickers is 25 more than
15 of Adam's stickers.
Adam has 250 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.
5 x 17 x 1 of Bryan's stickers =
1 x 55 x 5 of Adam's stickers + 25
57 of Bryan's stickers =
525 of Adam's stickers + 25
Let
125 of Adam's stickers be 1 u.
Number of stickers that Adam has = 25 u
25 u = 250
1 u = 250 ÷ 25 = 10
57 of Bryan's stickers = 5 u + 25
17 of Bryan's stickers = 1 u + 5
77 of Bryan's stickers = 7 u + 35
Number of stickers that Bryan has
= 7 u + 35
= 7 x 10 + 35
= 70 + 35
= 105
(b)
Number of stickers that Bryan and Adam have altogether
= 105 + 250
= 355
(c)
Number of stickers that Adam has more than Bryan
= 250 - 105
= 145
Answer(s): (a) 105; (b) 355; (c) 145
