Bryan and Adam have some stickers.
23 of Bryan's stickers is 48 less than
35 of Adam's stickers.
Adam has 160 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 - 48
69 of Bryan's stickers =
610 of Adam's stickers - 48
Let
110 of Adam's stickers be 1 u.
Number of stickers that Adam has = 10 u
10 u = 160
1 u = 160 ÷ 10 = 16
69 of Bryan's stickers = 6 u - 48
19 of Bryan's stickers = 1 u - 8
99 of Bryan's stickers = 9 u - 72
Number of stickers that Bryan has
= 9 u - 72
= 9 x 16 - 72
= 144 - 72
= 72
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 72 + 10 u
= 72 + 10 x 16
= 72 + 160
= 232
(c)
Number of stickers that Adam have more than Bryan
= 160 - 72
= 88
Answer(s): (a) 72; (b) 232; (c) 88
