45 of Bryan's money is equal to
13 of Adam's money.
Bryan has $30.
- 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.
45 of Bryan's money =
13 of Adam's money
4 x 15 x 1 of Bryan's money =
1 x 43 x 4 of Adam's money
45 of Bryan's money =
412 of Adam's money
5 u = 30
1 u = 30 ÷ 5 = 6
Amount that Adam has
= 12 u
= 12 x 6
= $72
(b)
Amount that Adam has more than Bryan
= 12 u - 5 u
= 7 u
= 7 x 6
= $42
(c)
Amount that they have altogether
= 5 u + 12 u
= 17 u
= 17 x 6
= $102
Answer(s): (a) $72; (b) $42; (c) $102
