Bryan and Adam have some stickers.
34 of Bryan's stickers is 72 less than
25 of Adam's stickers.
Adam has 210 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 - 72
68 of Bryan's stickers =
615 of Adam's stickers - 72
Let
115 of Adam's stickers be 1 u.
Number of stickers that Adam has = 15 u
15 u = 210
1 u = 210 ÷ 15 = 14
68 of Bryan's stickers = 6 u - 72
18 of Bryan's stickers = 1 u - 12
88 of Bryan's stickers = 8 u - 96
Number of stickers that Bryan has
= 8 u - 96
= 8 x 14 - 96
= 112 - 96
= 16
(b)
Number of stickers that Bryan and Adam have altogether
= 16 + 210
= 226
(c)
Number of stickers that Adam have more than Bryan
= 210 - 16
= 194
Answer(s): (a) 16; (b) 226; (c) 194
