Bryan and Adam have some stickers.
58 of Bryan's stickers is 40 more than
13 of Adam's stickers.
Adam has 180 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.
5 x 18 x 1 of Bryan's stickers =
1 x 53 x 5 of Adam's stickers + 40
58 of Bryan's stickers =
515 of Adam's stickers + 40
Let
115 of Adam's stickers be 1 u.
Number of stickers that Adam has = 15 u
15 u = 180
1 u = 180 ÷ 15 = 12
58 of Bryan's stickers = 5 u + 40
18 of Bryan's stickers = 1 u + 8
88 of Bryan's stickers = 8 u + 64
Number of stickers that Bryan has
= 8 u + 64
= 8 x 12 + 64
= 96 + 64
= 160
(b)
Number of stickers that Bryan and Adam have altogether
= 160 + 180
= 340
(c)
Number of stickers that Adam has more than Bryan
= 180 - 160
= 20
Answer(s): (a) 160; (b) 340; (c) 20
