23 of Bryan's money is equal to
47 of Adam's money.
Bryan has $90.
- How much does Adam have?
- How much does Adam have more than Bryan?
- How much do they have altogether?
(a)
Make the numerators the same.
23 of Bryan's money =
47 of Adam's money
2 x 23 x 2 of Bryan's money =
4 x 17 x 1 of Adam's money
46 of Bryan's money =
47 of Adam's money
6 u = 90
1 u = 90 ÷ 6 = 15
Amount that Adam has
= 7 u
= 7 x 15
= $105
(b)
Amount that Adam has more than Bryan
= 7 u - 6 u
= 1 u
= 1 x 15
= $15
(c)
Amount that they have altogether
= 6 u + 7 u
= 13 u
= 13 x 15
= $195
Answer(s): (a) $105; (b) $15; (c) $195
