45 of Adam's money is equal to
23 of Bryan's money.
Adam has $20.
- 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.
45 of Adam's money =
23 of Bryan's money
4 x 15 x 1 of Adam's money =
2 x 23 x 2 of Bryan's money
45 of Adam's money =
46 of Bryan's money
5 u = 20
1 u = 20 ÷ 5 = 4
Amount that Bryan has
= 6 u
= 6 x 4
= $24
(b)
Amount that Adam has less than Bryan
= 6 u - 5 u
= 1 u
= 1 x 4
= $4
(c)
Amount that they have altogether
= 5 u + 6 u
= 11 u
= 11 x 4
= $44
Answer(s): (a) $24; (b) $4; (c) $44
