Bryan and Adam have some stickers.
45 of Bryan's stickers is 40 more than
25 of Adam's stickers.
Adam has 230 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.
4 x 15 x 1 of Bryan's stickers =
2 x 25 x 2 of Adam's stickers + 40
45 of Bryan's stickers =
410 of Adam's stickers + 40
Let
110 of Adam's stickers be 1 u.
Number of stickers that Adam has = 10 u
10 u = 230
1 u = 230 ÷ 10 = 23
45 of Bryan's stickers = 4 u + 40
15 of Bryan's stickers = 1 u + 10
55 of Bryan's stickers = 5 u + 50
Number of stickers that Bryan has
= 5 u + 50
= 5 x 23 + 50
= 115 + 50
= 165
(b)
Number of stickers that Bryan and Adam have altogether
= 165 + 230
= 395
(c)
Number of stickers that Adam has more than Bryan
= 230 - 165
= 65
Answer(s): (a) 165; (b) 395; (c) 65
