12 of Adam's money is equal to
58 of Bryan's money.
Adam has $230.
- 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 18 x 1 of Bryan's money
510 of Adam's money =
58 of Bryan's money
Amount that Adam has = 10 u
Amount that Bryan has = 8 u
10 u = 230
1 u = 230 ÷ 10 = 23
Amount that Bryan has
= 8 u
= 8 x 23
= $184
(b)
Amount that Adam has more than Bryan
= 10 u - 8 u
= 2 u
= 2 x 23
= $46
(c)
Amount that they have altogether
= 10 u + 8 u
= 18 u
= 18 x 23
= $414
Answer(s): (a) $184; (b) $46; (c) $414
