23 of Adam's money is equal to
13 of Bryan's money.
Adam has $60.
- How much does Bryan have?
- How much does Adam have less than Bryan?
- How much do they have altogether?
(a)
Make the numerators the same.
23 of Adam's money =
13 of Bryan's money
2 x 13 x 1 of Adam's money =
1 x 23 x 2 of Bryan's money
23 of Adam's money =
26 of Bryan's money
3 u = 60
1 u = 60 ÷ 3 = 20
Amount that Bryan has
= 6 u
= 6 x 20
= $120
(b)
Amount that Adam has less than Bryan
= 6 u - 3 u
= 3 u
= 3 x 20
= $60
(c)
Amount that they have altogether
= 3 u + 6 u
= 9 u
= 9 x 20
= $180
Answer(s): (a) $120; (b) $60; (c) $180
