Adam and Bryan have some stickers.
23 of Adam's stickers is 30 less than
35 of Bryan's stickers.
Bryan has 250 stickers.
- How many stickers does Adam have?
- How many stickers do Adam and Bryan have altogether?
- How many stickers does Bryan have more than Adam?
(a)
Make the numerators the same.
2x33x3 of Adam's stickers =
3x25x2 of Bryan's stickers - 30
69 of Adam's stickers =
610 of Bryan's stickers - 30
Let
110 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 10 u
10 u = 250
1 u = 250 ÷ 10 = 25
69 of Adam's stickers = 6 u - 30
19 of Adam's stickers = 1 u - 5
99 of Adam's stickers = 9 u - 45
Number of stickers that Adam has
= 9 u - 45
= 9 x 25 - 45
= 225 - 45
= 180
(b)
Number of stickers that Adam and Bryan have altogether
= 9 u - 45 + 10 u
= 180 + 10 x 25
= 180 + 250
= 430
(c)
Number of stickers that Bryan have more than Adam
= 250 - 180
= 70
Answer(s): (a) 180; (b) 430; (c) 70
