Adam and Bryan have some stickers.
57 of Adam's stickers is 35 more than
16 of Bryan's stickers.
Bryan has 180 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 + 35
57 of Adam's stickers =
530 of Bryan's stickers + 35
Let
130 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 30 u
30 u = 180
1 u = 180 ÷ 30 = 6
57 of Adam's stickers = 5 u + 35
17 of Adam's stickers = 1 u + 7
77 of Adam's stickers = 7 u + 49
Number of stickers that Adam has
= 7 u + 49
= 7 x 6 + 49
= 42 + 49
= 91
(b)
Number of stickers that Adam and Bryan have altogether
= 91 + 180
= 271
(c)
Number of stickers that Bryan has more than Adam
= 180 - 91
= 89
Answer(s): (a) 91; (b) 271; (c) 89
