Adam and Bryan have some stickers.
45 of Adam's stickers is 20 more than
25 of Bryan's stickers.
Bryan has 190 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 =
2 x 25 x 2 of Bryan's stickers + 20
45 of Adam's stickers =
410 of Bryan's stickers + 20
Let
110 of Bryan's stickers be 1 u.
Number of stickers that Bryan has = 10 u
10 u = 190
1 u = 190 ÷ 10 = 19
45 of Adam's stickers = 4 u + 20
15 of Adam's stickers = 1 u + 5
55 of Adam's stickers = 5 u + 25
Number of stickers that Adam has
= 5 u + 25
= 5 x 19 + 25
= 95 + 25
= 120
(b)
Number of stickers that Adam and Bryan have altogether
= 120 + 190
= 310
(c)
Number of stickers that Bryan has more than Adam
= 190 - 120
= 70
Answer(s): (a) 120; (b) 310; (c) 70
