25 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 2 and 8.
LCM of 2 and 8 = 8
2 x 45 x 4 of Adam's money =
8 x 19 x 1 of Bryan's money
820 of Adam's money =
89 of Bryan's money
Amount that Adam has = 20 u
Amount that Bryan has = 9 u
20 u = 240
1 u = 240 ÷ 20 = 12
Amount that Bryan has
= 9 u
= 9 x 12
= $108
(b)
Amount that Adam has more than Bryan
= 20 u - 9 u
= 11 u
= 11 x 12
= $132
(c)
Amount that they have altogether
= 20 u + 9 u
= 29 u
= 29 x 12
= $348
Answer(s): (a) $108; (b) $132; (c) $348
