25 of Bryan's money is equal to
710 of Adam's money.
Bryan has $245.
- 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 2 and 7.
LCM of 2 and 7 = 14
2 x 75 x 7 of Bryan's money =
7 x 210 x 2 of Adam's money
1435 of Bryan's money =
1420 of Adam's money
Amount that Bryan has = 35 u
Amount that Adam has = 20 u
35 u = 245
1 u = 245 ÷ 35 = 7
Amount that Adam has
= 20 u
= 20 x 7
= $140
(b)
Amount that Bryan has more than Adam
= 35 u - 20 u
= 15 u
= 15 x 7
= $105
(c)
Amount that they have altogether
= 35 u + 20 u
= 55 u
= 55 x 7
= $385
Answer(s): (a) $140; (b) $105; (c) $385
