Bryan and Adam have some stickers.
45 of Bryan's stickers is 16 more than
18 of Adam's stickers.
Adam has 320 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 =
1 x 48 x 4 of Adam's stickers + 16
45 of Bryan's stickers =
432 of Adam's stickers + 16
Let
132 of Adam's stickers be 1 u.
Number of stickers that Adam has = 32 u
32 u = 320
1 u = 320 ÷ 32 = 10
45 of Bryan's stickers = 4 u + 16
15 of Bryan's stickers = 1 u + 4
55 of Bryan's stickers = 5 u + 20
Number of stickers that Bryan has
= 5 u + 20
= 5 x 10 + 20
= 50 + 20
= 70
(b)
Number of stickers that Bryan and Adam have altogether
= 70 + 320
= 390
(c)
Number of stickers that Adam has more than Bryan
= 320 - 70
= 250
Answer(s): (a) 70; (b) 390; (c) 250
