Bryan and Adam have some stickers.
23 of Bryan's stickers is 12 less than
35 of Adam's stickers.
Adam has 240 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 - 12
69 of Bryan's stickers =
610 of Adam's stickers - 12
Let
110 of Adam's stickers be 1 u.
Number of stickers that Adam has = 10 u
10 u = 240
1 u = 240 ÷ 10 = 24
69 of Bryan's stickers = 6 u - 12
19 of Bryan's stickers = 1 u - 2
99 of Bryan's stickers = 9 u - 18
Number of stickers that Bryan has
= 9 u - 18
= 9 x 24 - 18
= 216 - 18
= 198
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 18 + 10 u
= 198 + 10 x 24
= 198 + 240
= 438
(c)
Number of stickers that Adam have more than Bryan
= 240 - 198
= 42
Answer(s): (a) 198; (b) 438; (c) 42
