12 of Adam's money is equal to
57 of Bryan's money.
Adam has $110.
- 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 5.
LCM of 1 and 5 = 5
1 x 52 x 5 of Adam's money =
5 x 17 x 1 of Bryan's money
510 of Adam's money =
57 of Bryan's money
Amount that Adam has = 10 u
Amount that Bryan has = 7 u
10 u = 110
1 u = 110 ÷ 10 = 11
Amount that Bryan has
= 7 u
= 7 x 11
= $77
(b)
Amount that Adam has more than Bryan
= 10 u - 7 u
= 3 u
= 3 x 11
= $33
(c)
Amount that they have altogether
= 10 u + 7 u
= 17 u
= 17 x 11
= $187
Answer(s): (a) $77; (b) $33; (c) $187
