Bryan and Adam have some stickers.
23 of Bryan's stickers is 78 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 - 78
69 of Bryan's stickers =
614 of Adam's stickers - 78
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 - 78
19 of Bryan's stickers = 1 u - 13
99 of Bryan's stickers = 9 u - 117
Number of stickers that Bryan has
= 9 u - 117
= 9 x 19 - 117
= 171 - 117
= 54
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 117 + 14 u
= 54 + 14 x 19
= 54 + 266
= 320
(c)
Number of stickers that Adam have more than Bryan
= 266 - 54
= 212
Answer(s): (a) 54; (b) 320; (c) 212
