Bryan and Adam have some stickers.
23 of Bryan's stickers is 60 less than
35 of Adam's stickers.
Adam has 270 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 =
3x25x2 of Adam's stickers - 60
69 of Bryan's stickers =
610 of Adam's stickers - 60
Let
110 of Adam's stickers be 1 u.
Number of stickers that Adam has = 10 u
10 u = 270
1 u = 270 ÷ 10 = 27
69 of Bryan's stickers = 6 u - 60
19 of Bryan's stickers = 1 u - 10
99 of Bryan's stickers = 9 u - 90
Number of stickers that Bryan has
= 9 u - 90
= 9 x 27 - 90
= 243 - 90
= 153
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 90 + 10 u
= 153 + 10 x 27
= 153 + 270
= 423
(c)
Number of stickers that Adam have more than Bryan
= 270 - 153
= 117
Answer(s): (a) 153; (b) 423; (c) 117
