Bryan and Adam have some stickers.
23 of Bryan's stickers is 90 less than
37 of Adam's stickers.
Adam has 238 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.
2x33x3 of Bryan's stickers =
3x27x2 of Adam's stickers - 90
69 of Bryan's stickers =
614 of Adam's stickers - 90
Let
114 of Adam's stickers be 1 u.
Number of stickers that Adam has = 14 u
14 u = 238
1 u = 238 ÷ 14 = 17
69 of Bryan's stickers = 6 u - 90
19 of Bryan's stickers = 1 u - 15
99 of Bryan's stickers = 9 u - 135
Number of stickers that Bryan has
= 9 u - 135
= 9 x 17 - 135
= 153 - 135
= 18
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 135 + 14 u
= 18 + 14 x 17
= 18 + 238
= 256
(c)
Number of stickers that Adam have more than Bryan
= 238 - 18
= 220
Answer(s): (a) 18; (b) 256; (c) 220
