Bryan and Adam have some stickers.
47 of Bryan's stickers is 12 more than
25 of Adam's stickers.
Adam has 200 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 + 12
47 of Bryan's stickers =
410 of Adam's stickers + 12
Let
110 of Adam's stickers be 1 u.
Number of stickers that Adam has = 10 u
10 u = 200
1 u = 200 ÷ 10 = 20
47 of Bryan's stickers = 4 u + 12
17 of Bryan's stickers = 1 u + 3
77 of Bryan's stickers = 7 u + 21
Number of stickers that Bryan has
= 7 u + 21
= 7 x 20 + 21
= 140 + 21
= 161
(b)
Number of stickers that Bryan and Adam have altogether
= 161 + 200
= 361
(c)
Number of stickers that Adam has more than Bryan
= 200 - 161
= 39
Answer(s): (a) 161; (b) 361; (c) 39
