Bryan and Adam have some stickers.
45 of Bryan's stickers is 16 more than
25 of Adam's stickers.
Adam has 120 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 + 16
45 of Bryan's stickers =
410 of Adam's stickers + 16
Let
110 of Adam's stickers be 1 u.
Number of stickers that Adam has = 10 u
10 u = 120
1 u = 120 ÷ 10 = 12
45 of Bryan's stickers = 4 u + 16
15 of Bryan's stickers = 1 u + 4
55 of Bryan's stickers = 5 u + 20
Number of stickers that Bryan has
= 5 u + 20
= 5 x 12 + 20
= 60 + 20
= 80
(b)
Number of stickers that Bryan and Adam have altogether
= 80 + 120
= 200
(c)
Number of stickers that Adam has more than Bryan
= 120 - 80
= 40
Answer(s): (a) 80; (b) 200; (c) 40
