79 of Bryan's money is equal to
23 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.
79 of Bryan's money =
23 of Adam's money
7 x 29 x 2 of Bryan's money =
2 x 73 x 7 of Adam's money
1418 of Bryan's money =
1421 of Adam's money
18 u = 90
1 u = 90 ÷ 18 = 5
Amount that Adam has
= 21 u
= 21 x 5
= $105
(b)
Amount that Adam has more than Bryan
= 21 u - 18 u
= 3 u
= 3 x 5
= $15
(c)
Amount that they have altogether
= 18 u + 21 u
= 39 u
= 39 x 5
= $195
Answer(s): (a) $105; (b) $15; (c) $195
