23 of Bryan's money is equal to
12 of Adam's money.
Bryan has $60.
- How much does Adam have?
- How much does Bryan have less than Adam?
- How much do they have altogether?
(a)
Make the numerators the same.
23 of Bryan's money =
12 of Adam's money
2 x 13 x 1 of Bryan's money =
1 x 22 x 2 of Adam's money
23 of Bryan's money =
24 of Adam's money
3 u = 60
1 u = 60 ÷ 3 = 20
Amount that Adam has
= 4 u
= 4 x 20
= $80
(b)
Amount that Bryan has less than Adam
= 4 u - 3 u
= 1 u
= 1 x 20
= $20
(c)
Amount that they have altogether
= 3 u + 4 u
= 7 u
= 7 x 20
= $140
Answer(s): (a) $80; (b) $20; (c) $140
