Adam and Bryan have some stickers.
57 of Adam's stickers is 45 more than
16 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 17 x 1 of Adam's stickers =
1 x 56 x 5 of Bryan's stickers + 45
57 of Adam's stickers =
530 of Bryan's stickers + 45
Let
130 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 30 u
30 u = 300
1 u = 300 ÷ 30 = 10
57 of Adam's stickers = 5 u + 45
17 of Adam's stickers = 1 u + 9
77 of Adam's stickers = 7 u + 63
Number of stickers that Adam has
= 7 u + 63
= 7 x 10 + 63
= 70 + 63
= 133
(b)
Number of stickers that Adam and Bryan have altogether
= 133 + 300
= 433
(c)
Number of stickers that Bryan has more than Adam
= 300 - 133
= 167
Answer(s): (a) 133; (b) 433; (c) 167
