45 of Bryan's money is equal to
23 of Adam's money.
Bryan has $90.
- How much does Adam have?
- How much does Bryan have less than Adam?
- 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 = 90
1 u = 90 ÷ 5 = 18
Amount that Adam has
= 6 u
= 6 x 18
= $108
(b)
Amount that Bryan has less than Adam
= 6 u - 5 u
= 1 u
= 1 x 18
= $18
(c)
Amount that they have altogether
= 5 u + 6 u
= 11 u
= 11 x 18
= $198
Answer(s): (a) $108; (b) $18; (c) $198
