12 of Adam's money is equal to
89 of Bryan's money.
Adam has $240.
- 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 8.
LCM of 1 and 8 = 8
1 x 82 x 8 of Adam's money =
8 x 19 x 1 of Bryan's money
816 of Adam's money =
89 of Bryan's money
Amount that Adam has = 16 u
Amount that Bryan has = 9 u
16 u = 240
1 u = 240 ÷ 16 = 15
Amount that Bryan has
= 9 u
= 9 x 15
= $135
(b)
Amount that Adam has more than Bryan
= 16 u - 9 u
= 7 u
= 7 x 15
= $105
(c)
Amount that they have altogether
= 16 u + 9 u
= 25 u
= 25 x 15
= $375
Answer(s): (a) $135; (b) $105; (c) $375
