Bryan and Adam have some stickers.
23 of Bryan's stickers is 18 less than
38 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 =
3x28x2 of Adam's stickers - 18
69 of Bryan's stickers =
616 of Adam's stickers - 18
Let
116 of Adam's stickers be 1 u.
Number of stickers that Adam has = 16 u
16 u = 240
1 u = 240 ÷ 16 = 15
69 of Bryan's stickers = 6 u - 18
19 of Bryan's stickers = 1 u - 3
99 of Bryan's stickers = 9 u - 27
Number of stickers that Bryan has
= 9 u - 27
= 9 x 15 - 27
= 135 - 27
= 108
(b)
Number of stickers that Bryan and Adam have altogether
= 9 u - 27 + 16 u
= 108 + 16 x 15
= 108 + 240
= 348
(c)
Number of stickers that Adam have more than Bryan
= 240 - 108
= 132
Answer(s): (a) 108; (b) 348; (c) 132
