13 of Adam's money is equal to
34 of Bryan's money.
Adam has $243.
- 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 3.
LCM of 1 and 3 = 3
1 x 33 x 3 of Adam's money =
3 x 14 x 1 of Bryan's money
39 of Adam's money =
34 of Bryan's money
Amount that Adam has = 9 u
Amount that Bryan has = 4 u
9 u = 243
1 u = 243 ÷ 9 = 27
Amount that Bryan has
= 4 u
= 4 x 27
= $108
(b)
Amount that Adam has more than Bryan
= 9 u - 4 u
= 5 u
= 5 x 27
= $135
(c)
Amount that they have altogether
= 9 u + 4 u
= 13 u
= 13 x 27
= $351
Answer(s): (a) $108; (b) $135; (c) $351
