57 of Bryan's money is equal to
12 of Adam's money.
Bryan has $70.
- 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.
57 of Bryan's money =
12 of Adam's money
5 x 17 x 1 of Bryan's money =
1 x 52 x 5 of Adam's money
57 of Bryan's money =
510 of Adam's money
7 u = 70
1 u = 70 ÷ 7 = 10
Amount that Adam has
= 10 u
= 10 x 10
= $100
(b)
Amount that Adam has more than Bryan
= 10 u - 7 u
= 3 u
= 3 x 10
= $30
(c)
Amount that they have altogether
= 7 u + 10 u
= 17 u
= 17 x 10
= $170
Answer(s): (a) $100; (b) $30; (c) $170
