15 of Adam's money is equal to
34 of Bryan's money.
Adam has $120.
- 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 3.
LCM of 1 and 3 = 3
1 x 35 x 3 of Adam's money =
3 x 14 x 1 of Bryan's money
315 of Adam's money =
34 of Bryan's money
Amount that Adam has = 15 u
Amount that Bryan has = 4 u
15 u = 120
1 u = 120 ÷ 15 = 8
Amount that Bryan has
= 4 u
= 4 x 8
= $32
(b)
Amount that Adam has more than Bryan
= 15 u - 4 u
= 11 u
= 11 x 8
= $88
(c)
Amount that they have altogether
= 15 u + 4 u
= 19 u
= 19 x 8
= $152
Answer(s): (a) $32; (b) $88; (c) $152
