Bryan and Adam have some stickers.
23 of Bryan's stickers is 84 less than
35 of Adam's stickers.
Adam has 150 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 - 84
69 of Bryan's stickers =
610 of Adam's stickers - 84
Let
110 of Adam's stickers be 1 u.
Number of stickers that Adam has = 10 u
10 u = 150
1 u = 150 ÷ 10 = 15
69 of Bryan's stickers = 6 u - 84
19 of Bryan's stickers = 1 u - 14
99 of Bryan's stickers = 9 u - 126
Number of stickers that Bryan has
= 9 u - 126
= 9 x 15 - 126
= 135 - 126
= 9
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 126 + 10 u
= 9 + 10 x 15
= 9 + 150
= 159
(c)
Number of stickers that Adam have more than Bryan
= 150 - 9
= 141
Answer(s): (a) 9; (b) 159; (c) 141
