13 of Adam's money is equal to
45 of Bryan's money.
Adam has $192.
- 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 4.
LCM of 1 and 4 = 4
1 x 43 x 4 of Adam's money =
4 x 15 x 1 of Bryan's money
412 of Adam's money =
45 of Bryan's money
Amount that Adam has = 12 u
Amount that Bryan has = 5 u
12 u = 192
1 u = 192 ÷ 12 = 16
Amount that Bryan has
= 5 u
= 5 x 16
= $80
(b)
Amount that Adam has more than Bryan
= 12 u - 5 u
= 7 u
= 7 x 16
= $112
(c)
Amount that they have altogether
= 12 u + 5 u
= 17 u
= 17 x 16
= $272
Answer(s): (a) $80; (b) $112; (c) $272
