110 of Bryan's money is equal to
710 of Adam's money.
Bryan has $210.
- 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 710 x 7 of Bryan's money =
7 x 110 x 1 of Adam's money
770 of Bryan's money =
710 of Adam's money
Amount that Bryan has = 70 u
Amount that Adam has = 10 u
70 u = 210
1 u = 210 ÷ 70 = 3
Amount that Adam has
= 10 u
= 10 x 3
= $30
(b)
Amount that Bryan has more than Adam
= 70 u - 10 u
= 60 u
= 60 x 3
= $180
(c)
Amount that they have altogether
= 70 u + 10 u
= 80 u
= 80 x 3
= $240
Answer(s): (a) $30; (b) $180; (c) $240
