Bryan and Adam have some stickers.
23 of Bryan's stickers is 30 less than
37 of Adam's stickers.
Adam has 266 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 - 30
69 of Bryan's stickers =
614 of Adam's stickers - 30
Let
114 of Adam's stickers be 1 u.
Number of stickers that Adam has = 14 u
14 u = 266
1 u = 266 ÷ 14 = 19
69 of Bryan's stickers = 6 u - 30
19 of Bryan's stickers = 1 u - 5
99 of Bryan's stickers = 9 u - 45
Number of stickers that Bryan has
= 9 u - 45
= 9 x 19 - 45
= 171 - 45
= 126
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 45 + 14 u
= 126 + 14 x 19
= 126 + 266
= 392
(c)
Number of stickers that Adam have more than Bryan
= 266 - 126
= 140
Answer(s): (a) 126; (b) 392; (c) 140
