Bryan and Adam have some stickers.
38 of Bryan's stickers is 45 more than
16 of Adam's stickers.
Adam has 360 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.
3 x 18 x 1 of Bryan's stickers =
1 x 36 x 3 of Adam's stickers + 45
38 of Bryan's stickers =
318 of Adam's stickers + 45
Let
118 of Adam's stickers be 1 u.
Number of stickers that Adam has = 18 u
18 u = 360
1 u = 360 ÷ 18 = 20
38 of Bryan's stickers = 3 u + 45
18 of Bryan's stickers = 1 u + 15
88 of Bryan's stickers = 8 u + 120
Number of stickers that Bryan has
= 8 u + 120
= 8 x 20 + 120
= 160 + 120
= 280
(b)
Number of stickers that Bryan and Adam have altogether
= 280 + 360
= 640
(c)
Number of stickers that Adam has more than Bryan
= 360 - 280
= 80
Answer(s): (a) 280; (b) 640; (c) 80
