12 of Adam's money is equal to
56 of Bryan's money.
Adam has $180.
- How much does Bryan have?
- How much does Adam have more than Bryan?
- How much do they have altogether?
(a)
Make the numerators the same using the LCM of 1 and 5.
LCM of 1 and 5 = 5
1 x 52 x 5 of Adam's money =
5 x 16 x 1 of Bryan's money
510 of Adam's money =
56 of Bryan's money
Amount that Adam has = 10 u
Amount that Bryan has = 6 u
10 u = 180
1 u = 180 ÷ 10 = 18
Amount that Bryan has
= 6 u
= 6 x 18
= $108
(b)
Amount that Adam has more than Bryan
= 10 u - 6 u
= 4 u
= 4 x 18
= $72
(c)
Amount that they have altogether
= 10 u + 6 u
= 16 u
= 16 x 18
= $288
Answer(s): (a) $108; (b) $72; (c) $288
