25 of Bryan's money is equal to
15 of Adam's money.
Bryan has $40.
- 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.
25 of Bryan's money =
15 of Adam's money
2 x 15 x 1 of Bryan's money =
1 x 25 x 2 of Adam's money
25 of Bryan's money =
210 of Adam's money
5 u = 40
1 u = 40 ÷ 5 = 8
Amount that Adam has
= 10 u
= 10 x 8
= $80
(b)
Amount that Bryan has less than Adam
= 10 u - 5 u
= 5 u
= 5 x 8
= $40
(c)
Amount that they have altogether
= 5 u + 10 u
= 15 u
= 15 x 8
= $120
Answer(s): (a) $80; (b) $40; (c) $120
