Bryan and Adam have some stickers.
47 of Bryan's stickers is 40 more than
25 of Adam's stickers.
Adam has 240 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 17 x 1 of Bryan's stickers =
2 x 25 x 2 of Adam's stickers + 40
47 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 = 240
1 u = 240 ÷ 10 = 24
47 of Bryan's stickers = 4 u + 40
17 of Bryan's stickers = 1 u + 10
77 of Bryan's stickers = 7 u + 70
Number of stickers that Bryan has
= 7 u + 70
= 7 x 24 + 70
= 168 + 70
= 238
(b)
Number of stickers that Bryan and Adam have altogether
= 238 + 240
= 478
(c)
Number of stickers that Adam has more than Bryan
= 240 - 238
= 2
Answer(s): (a) 238; (b) 478; (c) 2
