12 of Bryan's money is equal to
89 of Adam's money.
Bryan has $272.
- How much does Adam have?
- How much does Bryan have more than Adam?
- How much do they have altogether?
(a)
Make the numerators the same using the LCM of 1 and 8.
LCM of 1 and 8 = 8
1 x 82 x 8 of Bryan's money =
8 x 19 x 1 of Adam's money
816 of Bryan's money =
89 of Adam's money
Amount that Bryan has = 16 u
Amount that Adam has = 9 u
16 u = 272
1 u = 272 ÷ 16 = 17
Amount that Adam has
= 9 u
= 9 x 17
= $153
(b)
Amount that Bryan has more than Adam
= 16 u - 9 u
= 7 u
= 7 x 17
= $119
(c)
Amount that they have altogether
= 16 u + 9 u
= 25 u
= 25 x 17
= $425
Answer(s): (a) $153; (b) $119; (c) $425
