12 of Bryan's money is equal to
710 of Adam's money.
Bryan has $252.
- 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 7.
LCM of 1 and 7 = 7
1 x 72 x 7 of Bryan's money =
7 x 110 x 1 of Adam's money
714 of Bryan's money =
710 of Adam's money
Amount that Bryan has = 14 u
Amount that Adam has = 10 u
14 u = 252
1 u = 252 ÷ 14 = 18
Amount that Adam has
= 10 u
= 10 x 18
= $180
(b)
Amount that Bryan has more than Adam
= 14 u - 10 u
= 4 u
= 4 x 18
= $72
(c)
Amount that they have altogether
= 14 u + 10 u
= 24 u
= 24 x 18
= $432
Answer(s): (a) $180; (b) $72; (c) $432
