45 of Bryan's money is equal to
25 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 =
25 of Adam's money
4 x 15 x 1 of Bryan's money =
2 x 25 x 2 of Adam's money
45 of Bryan's money =
410 of Adam's money
5 u = 30
1 u = 30 ÷ 5 = 6
Amount that Adam has
= 10 u
= 10 x 6
= $60
(b)
Amount that Adam has more than Bryan
= 10 u - 5 u
= 5 u
= 5 x 6
= $30
(c)
Amount that they have altogether
= 5 u + 10 u
= 15 u
= 15 x 6
= $90
Answer(s): (a) $60; (b) $30; (c) $90
