38 of Bryan's money is equal to
13 of Adam's money.
Bryan has $80.
- 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.
38 of Bryan's money =
13 of Adam's money
3 x 18 x 1 of Bryan's money =
1 x 33 x 3 of Adam's money
38 of Bryan's money =
39 of Adam's money
8 u = 80
1 u = 80 ÷ 8 = 10
Amount that Adam has
= 9 u
= 9 x 10
= $90
(b)
Amount that Adam has more than Bryan
= 9 u - 8 u
= 1 u
= 1 x 10
= $10
(c)
Amount that they have altogether
= 8 u + 9 u
= 17 u
= 17 x 10
= $170
Answer(s): (a) $90; (b) $10; (c) $170
