Bryan and Adam have some stickers.
23 of Bryan's stickers is 90 less than
38 of Adam's stickers.
Adam has 256 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 =
3x28x2 of Adam's stickers - 90
69 of Bryan's stickers =
616 of Adam's stickers - 90
Let
116 of Adam's stickers be 1 u.
Number of stickers that Adam has = 16 u
16 u = 256
1 u = 256 ÷ 16 = 16
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 16 - 135
= 144 - 135
= 9
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 135 + 16 u
= 9 + 16 x 16
= 9 + 256
= 265
(c)
Number of stickers that Adam have more than Bryan
= 256 - 9
= 247
Answer(s): (a) 9; (b) 265; (c) 247
