Adam and Bryan have some stickers.
57 of Adam's stickers is 30 more than
25 of Bryan's stickers.
Bryan has 300 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.
5 x 27 x 2 of Adam's stickers =
2 x 55 x 5 of Bryan's stickers + 30
1014 of Adam's stickers =
1025 of Bryan's stickers + 30
Let
125 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 25 u
25 u = 300
1 u = 300 ÷ 25 = 12
1014 of Adam's stickers = 10 u + 30
114 of Adam's stickers = 1 u + 3
1414 of Adam's stickers = 14 u + 42
Number of stickers that Adam has
= 14 u + 42
= 14 x 12 + 42
= 168 + 42
= 210
(b)
Number of stickers that Adam and Bryan have altogether
= 210 + 300
= 510
(c)
Number of stickers that Bryan has more than Adam
= 300 - 210
= 90
Answer(s): (a) 210; (b) 510; (c) 90
