49 of Bryan's money is equal to
25 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.
49 of Bryan's money =
25 of Adam's money
4 x 19 x 1 of Bryan's money =
2 x 25 x 2 of Adam's money
49 of Bryan's money =
410 of Adam's money
9 u = 90
1 u = 90 ÷ 9 = 10
Amount that Adam has
= 10 u
= 10 x 10
= $100
(b)
Amount that Adam has more than Bryan
= 10 u - 9 u
= 1 u
= 1 x 10
= $10
(c)
Amount that they have altogether
= 9 u + 10 u
= 19 u
= 19 x 10
= $190
Answer(s): (a) $100; (b) $10; (c) $190
