13 of Bryan's money is equal to
34 of Adam's money.
Bryan has $180.
- How much does Adam have?
- How much does Bryan have more than Adam?
- How much do they have altogether?
(a)
Make the numerators the same using the LCM of 1 and 3.
LCM of 1 and 3 = 3
1 x 33 x 3 of Bryan's money =
3 x 14 x 1 of Adam's money
39 of Bryan's money =
34 of Adam's money
Amount that Bryan has = 9 u
Amount that Adam has = 4 u
9 u = 180
1 u = 180 ÷ 9 = 20
Amount that Adam has
= 4 u
= 4 x 20
= $80
(b)
Amount that Bryan has more than Adam
= 9 u - 4 u
= 5 u
= 5 x 20
= $100
(c)
Amount that they have altogether
= 9 u + 4 u
= 13 u
= 13 x 20
= $260
Answer(s): (a) $80; (b) $100; (c) $260
