Bryan and Adam have some stickers.
45 of Bryan's stickers is 12 more than
25 of Adam's stickers.
Adam has 100 stickers.
- How many stickers does Bryan have?
- How many stickers do Bryan and Adam have altogether?
- How many stickers does Adam have more than Bryan?
(a)
Make the numerators the same.
4 x 15 x 1 of Bryan's stickers =
2 x 25 x 2 of Adam's stickers + 12
45 of Bryan's stickers =
410 of Adam's stickers + 12
Let
110 of Adam's stickers be 1 u.
Number of stickers that Adam has = 10 u
10 u = 100
1 u = 100 ÷ 10 = 10
45 of Bryan's stickers = 4 u + 12
15 of Bryan's stickers = 1 u + 3
55 of Bryan's stickers = 5 u + 15
Number of stickers that Bryan has
= 5 u + 15
= 5 x 10 + 15
= 50 + 15
= 65
(b)
Number of stickers that Bryan and Adam have altogether
= 65 + 100
= 165
(c)
Number of stickers that Adam has more than Bryan
= 100 - 65
= 35
Answer(s): (a) 65; (b) 165; (c) 35
