Bryan and Adam have some stickers.
23 of Bryan's stickers is 72 less than
35 of Adam's stickers.
Adam has 130 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 - 72
69 of Bryan's stickers =
610 of Adam's stickers - 72
Let
110 of Adam's stickers be 1 u.
Number of stickers that Adam has = 10 u
10 u = 130
1 u = 130 ÷ 10 = 13
69 of Bryan's stickers = 6 u - 72
19 of Bryan's stickers = 1 u - 12
99 of Bryan's stickers = 9 u - 108
Number of stickers that Bryan has
= 9 u - 108
= 9 x 13 - 108
= 117 - 108
= 9
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 108 + 10 u
= 9 + 10 x 13
= 9 + 130
= 139
(c)
Number of stickers that Adam have more than Bryan
= 130 - 9
= 121
Answer(s): (a) 9; (b) 139; (c) 121
