25 of Adam's money is equal to
47 of Bryan's money.
Adam has $120.
- 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 2 and 4.
LCM of 2 and 4 = 4
2 x 25 x 2 of Adam's money =
4 x 17 x 1 of Bryan's money
410 of Adam's money =
47 of Bryan's money
Amount that Adam has = 10 u
Amount that Bryan has = 7 u
10 u = 120
1 u = 120 ÷ 10 = 12
Amount that Bryan has
= 7 u
= 7 x 12
= $84
(b)
Amount that Adam has more than Bryan
= 10 u - 7 u
= 3 u
= 3 x 12
= $36
(c)
Amount that they have altogether
= 10 u + 7 u
= 17 u
= 17 x 12
= $204
Answer(s): (a) $84; (b) $36; (c) $204
