Bryan and Adam have some stickers.
47 of Bryan's stickers is 20 more than
25 of Adam's stickers.
Adam has 350 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 + 20
47 of Bryan's stickers =
410 of Adam's stickers + 20
Let
110 of Adam's stickers be 1 u.
Number of stickers that Adam has = 10 u
10 u = 350
1 u = 350 ÷ 10 = 35
47 of Bryan's stickers = 4 u + 20
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 35 + 35
= 245 + 35
= 280
(b)
Number of stickers that Bryan and Adam have altogether
= 280 + 350
= 630
(c)
Number of stickers that Adam has more than Bryan
= 350 - 280
= 70
Answer(s): (a) 280; (b) 630; (c) 70
