Adam and Bryan have some stickers.
38 of Adam's stickers is 45 more than
15 of Bryan's stickers.
Bryan has 390 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 + 45
38 of Adam's stickers =
315 of Bryan's stickers + 45
Let
115 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 15 u
15 u = 390
1 u = 390 ÷ 15 = 26
38 of Adam's stickers = 3 u + 45
18 of Adam's stickers = 1 u + 15
88 of Adam's stickers = 8 u + 120
Number of stickers that Adam has
= 8 u + 120
= 8 x 26 + 120
= 208 + 120
= 328
(b)
Number of stickers that Adam and Bryan have altogether
= 328 + 390
= 718
(c)
Number of stickers that Bryan has more than Adam
= 390 - 328
= 62
Answer(s): (a) 328; (b) 718; (c) 62
