18 of Bryan's money is equal to
29 of Adam's money.
Bryan has $128.
- How much does Adam have?
- How much does Bryan have more than Adam?
- How much do they have altogether?
(a)
Make the numerators the same using the LCM of 1 and 2.
LCM of 1 and 2 = 2
1 x 28 x 2 of Bryan's money =
2 x 19 x 1 of Adam's money
216 of Bryan's money =
29 of Adam's money
Amount that Bryan has = 16 u
Amount that Adam has = 9 u
16 u = 128
1 u = 128 ÷ 16 = 8
Amount that Adam has
= 9 u
= 9 x 8
= $72
(b)
Amount that Bryan has more than Adam
= 16 u - 9 u
= 7 u
= 7 x 8
= $56
(c)
Amount that they have altogether
= 16 u + 9 u
= 25 u
= 25 x 8
= $200
Answer(s): (a) $72; (b) $56; (c) $200
