25 of Adam's money is equal to
45 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 15 x 1 of Bryan's money
410 of Adam's money =
45 of Bryan's money
Amount that Adam has = 10 u
Amount that Bryan has = 5 u
10 u = 120
1 u = 120 ÷ 10 = 12
Amount that Bryan has
= 5 u
= 5 x 12
= $60
(b)
Amount that Adam has more than Bryan
= 10 u - 5 u
= 5 u
= 5 x 12
= $60
(c)
Amount that they have altogether
= 10 u + 5 u
= 15 u
= 15 x 12
= $180
Answer(s): (a) $60; (b) $60; (c) $180
