12 of Adam's money is equal to
25 of Bryan's money.
Adam has $80.
- How much does Bryan have?
- How much does Bryan have more than Adam?
- How much do they have altogether?
(a)
Make the numerators the same.
12 of Adam's money =
25 of Bryan's money
1 x 22 x 2 of Adam's money =
2 x 15 x 1 of Bryan's money
24 of Adam's money =
25 of Bryan's money
4 u = 80
1 u = 80 ÷ 4 = 20
Amount that Bryan has
= 5 u
= 5 x 20
= $100
(b)
Amount that Bryan has more than Adam
= 5 u - 4 u
= 1 u
= 1 x 20
= $20
(c)
Amount that they have altogether
= 4 u + 5 u
= 9 u
= 9 x 20
= $180
Answer(s): (a) $100; (b) $20; (c) $180
