Adam and Bryan have some stickers.
38 of Adam's stickers is 15 more than
15 of Bryan's stickers.
Bryan has 120 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 18 x 1 of Adam's stickers =
1 x 35 x 3 of Bryan's stickers + 15
38 of Adam's stickers =
315 of Bryan's stickers + 15
Let
115 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 15 u
15 u = 120
1 u = 120 ÷ 15 = 8
38 of Adam's stickers = 3 u + 15
18 of Adam's stickers = 1 u + 5
88 of Adam's stickers = 8 u + 40
Number of stickers that Adam has
= 8 u + 40
= 8 x 8 + 40
= 64 + 40
= 104
(b)
Number of stickers that Adam and Bryan have altogether
= 104 + 120
= 224
(c)
Number of stickers that Bryan has more than Adam
= 120 - 104
= 16
Answer(s): (a) 104; (b) 224; (c) 16
