Adam and Bryan have some stickers.
47 of Adam's stickers is 44 more than
15 of Bryan's stickers.
Bryan has 200 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 17 x 1 of Adam's stickers =
1 x 45 x 4 of Bryan's stickers + 44
47 of Adam's stickers =
420 of Bryan's stickers + 44
Let
120 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 20 u
20 u = 200
1 u = 200 ÷ 20 = 10
47 of Adam's stickers = 4 u + 44
17 of Adam's stickers = 1 u + 11
77 of Adam's stickers = 7 u + 77
Number of stickers that Adam has
= 7 u + 77
= 7 x 10 + 77
= 70 + 77
= 147
(b)
Number of stickers that Adam and Bryan have altogether
= 147 + 200
= 347
(c)
Number of stickers that Bryan has more than Adam
= 200 - 147
= 53
Answer(s): (a) 147; (b) 347; (c) 53
