Bryan and Adam have some stickers.
45 of Bryan's stickers is 40 more than
23 of Adam's stickers.
Adam has 390 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 + 40
45 of Bryan's stickers =
46 of Adam's stickers + 40
Let
16 of Adam's stickers be 1 u.
Number of stickers that Adam has = 6 u
6 u = 390
1 u = 390 ÷ 6 = 65
45 of Bryan's stickers = 4 u + 40
15 of Bryan's stickers = 1 u + 10
55 of Bryan's stickers = 5 u + 50
Number of stickers that Bryan has
= 5 u + 50
= 5 x 65 + 50
= 325 + 50
= 375
(b)
Number of stickers that Bryan and Adam have altogether
= 375 + 390
= 765
(c)
Number of stickers that Adam has more than Bryan
= 390 - 375
= 15
Answer(s): (a) 375; (b) 765; (c) 15
