19 of Adam's money is equal to
23 of Bryan's money.
Adam has $180.
- 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 1 and 2.
LCM of 1 and 2 = 2
1 x 29 x 2 of Adam's money =
2 x 13 x 1 of Bryan's money
218 of Adam's money =
23 of Bryan's money
Amount that Adam has = 18 u
Amount that Bryan has = 3 u
18 u = 180
1 u = 180 ÷ 18 = 10
Amount that Bryan has
= 3 u
= 3 x 10
= $30
(b)
Amount that Adam has more than Bryan
= 18 u - 3 u
= 15 u
= 15 x 10
= $150
(c)
Amount that they have altogether
= 18 u + 3 u
= 21 u
= 21 x 10
= $210
Answer(s): (a) $30; (b) $150; (c) $210
