Bryan and Adam have some stickers.
23 of Bryan's stickers is 42 less than
35 of Adam's stickers.
Adam has 120 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 - 42
69 of Bryan's stickers =
610 of Adam's stickers - 42
Let
110 of Adam's stickers be 1 u.
Number of stickers that Adam has = 10 u
10 u = 120
1 u = 120 ÷ 10 = 12
69 of Bryan's stickers = 6 u - 42
19 of Bryan's stickers = 1 u - 7
99 of Bryan's stickers = 9 u - 63
Number of stickers that Bryan has
= 9 u - 63
= 9 x 12 - 63
= 108 - 63
= 45
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 63 + 10 u
= 45 + 10 x 12
= 45 + 120
= 165
(c)
Number of stickers that Adam have more than Bryan
= 120 - 45
= 75
Answer(s): (a) 45; (b) 165; (c) 75
