Adam and Bryan have some stickers.
37 of Adam's stickers is 12 more than
18 of Bryan's stickers.
Bryan has 360 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.
3 x 17 x 1 of Adam's stickers =
1 x 38 x 3 of Bryan's stickers + 12
37 of Adam's stickers =
324 of Bryan's stickers + 12
Let
124 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 24 u
24 u = 360
1 u = 360 ÷ 24 = 15
37 of Adam's stickers = 3 u + 12
17 of Adam's stickers = 1 u + 4
77 of Adam's stickers = 7 u + 28
Number of stickers that Adam has
= 7 u + 28
= 7 x 15 + 28
= 105 + 28
= 133
(b)
Number of stickers that Adam and Bryan have altogether
= 133 + 360
= 493
(c)
Number of stickers that Bryan has more than Adam
= 360 - 133
= 227
Answer(s): (a) 133; (b) 493; (c) 227
