Bryan and Adam have some stickers.
35 of Bryan's stickers is 45 more than
15 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.
3 x 15 x 1 of Bryan's stickers =
1 x 35 x 3 of Adam's stickers + 45
35 of Bryan's stickers =
315 of Adam's stickers + 45
Let
115 of Adam's stickers be 1 u.
Number of stickers that Adam has = 15 u
15 u = 330
1 u = 330 ÷ 15 = 22
35 of Bryan's stickers = 3 u + 45
15 of Bryan's stickers = 1 u + 15
55 of Bryan's stickers = 5 u + 75
Number of stickers that Bryan has
= 5 u + 75
= 5 x 22 + 75
= 110 + 75
= 185
(b)
Number of stickers that Bryan and Adam have altogether
= 185 + 330
= 515
(c)
Number of stickers that Adam has more than Bryan
= 330 - 185
= 145
Answer(s): (a) 185; (b) 515; (c) 145
