Adam and Bryan have some stickers.
47 of Adam's stickers is 32 more than
15 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.
4 x 17 x 1 of Adam's stickers =
1 x 45 x 4 of Bryan's stickers + 32
47 of Adam's stickers =
420 of Bryan's stickers + 32
Let
120 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 20 u
20 u = 300
1 u = 300 ÷ 20 = 15
47 of Adam's stickers = 4 u + 32
17 of Adam's stickers = 1 u + 8
77 of Adam's stickers = 7 u + 56
Number of stickers that Adam has
= 7 u + 56
= 7 x 15 + 56
= 105 + 56
= 161
(b)
Number of stickers that Adam and Bryan have altogether
= 161 + 300
= 461
(c)
Number of stickers that Bryan has more than Adam
= 300 - 161
= 139
Answer(s): (a) 161; (b) 461; (c) 139
