Bryan and Adam have some stickers.
45 of Bryan's stickers is 28 more than
23 of Adam's stickers.
Adam has 330 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 23 x 2 of Adam's stickers + 28
45 of Bryan's stickers =
46 of Adam's stickers + 28
Let
16 of Adam's stickers be 1 u.
Number of stickers that Adam has = 6 u
6 u = 330
1 u = 330 ÷ 6 = 55
45 of Bryan's stickers = 4 u + 28
15 of Bryan's stickers = 1 u + 7
55 of Bryan's stickers = 5 u + 35
Number of stickers that Bryan has
= 5 u + 35
= 5 x 55 + 35
= 275 + 35
= 310
(b)
Number of stickers that Bryan and Adam have altogether
= 310 + 330
= 640
(c)
Number of stickers that Adam has more than Bryan
= 330 - 310
= 20
Answer(s): (a) 310; (b) 640; (c) 20
