45 of Bryan's money is equal to
23 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.
45 of Bryan's money =
23 of Adam's money
4 x 15 x 1 of Bryan's money =
2 x 23 x 2 of Adam's money
45 of Bryan's money =
46 of Adam's money
5 u = 80
1 u = 80 ÷ 5 = 16
Amount that Adam has
= 6 u
= 6 x 16
= $96
(b)
Amount that Adam has more than Bryan
= 6 u - 5 u
= 1 u
= 1 x 16
= $16
(c)
Amount that they have altogether
= 5 u + 6 u
= 11 u
= 11 x 16
= $176
Answer(s): (a) $96; (b) $16; (c) $176
