18 of Adam's money is equal to
49 of Bryan's money.
Adam has $128.
- 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 4.
LCM of 1 and 4 = 4
1 x 48 x 4 of Adam's money =
4 x 19 x 1 of Bryan's money
432 of Adam's money =
49 of Bryan's money
Amount that Adam has = 32 u
Amount that Bryan has = 9 u
32 u = 128
1 u = 128 ÷ 32 = 4
Amount that Bryan has
= 9 u
= 9 x 4
= $36
(b)
Amount that Adam has more than Bryan
= 32 u - 9 u
= 23 u
= 23 x 4
= $92
(c)
Amount that they have altogether
= 32 u + 9 u
= 41 u
= 41 x 4
= $164
Answer(s): (a) $36; (b) $92; (c) $164
