Adam and Bryan have some stickers.
45 of Adam's stickers is 28 more than
15 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.
4 x 15 x 1 of Adam's stickers =
1 x 45 x 4 of Bryan's stickers + 28
45 of Adam's stickers =
420 of Bryan's stickers + 28
Let
120 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 20 u
20 u = 360
1 u = 360 ÷ 20 = 18
45 of Adam's stickers = 4 u + 28
15 of Adam's stickers = 1 u + 7
55 of Adam's stickers = 5 u + 35
Number of stickers that Adam has
= 5 u + 35
= 5 x 18 + 35
= 90 + 35
= 125
(b)
Number of stickers that Adam and Bryan have altogether
= 125 + 360
= 485
(c)
Number of stickers that Bryan has more than Adam
= 360 - 125
= 235
Answer(s): (a) 125; (b) 485; (c) 235
