Bryan and Adam have some stickers.
34 of Bryan's stickers is 66 less than
25 of Adam's stickers.
Adam has 225 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.
3x24x2 of Bryan's stickers =
2x35x3 of Adam's stickers - 66
68 of Bryan's stickers =
615 of Adam's stickers - 66
Let
115 of Adam's stickers be 1 u.
Number of stickers that Adam has = 15 u
15 u = 225
1 u = 225 ÷ 15 = 15
68 of Bryan's stickers = 6 u - 66
18 of Bryan's stickers = 1 u - 11
88 of Bryan's stickers = 8 u - 88
Number of stickers that Bryan has
= 8 u - 88
= 8 x 15 - 88
= 120 - 88
= 32
(b)
Number of stickers that Bryan and Adam have altogether
= 32 + 225
= 257
(c)
Number of stickers that Adam have more than Bryan
= 225 - 32
= 193
Answer(s): (a) 32; (b) 257; (c) 193
