38 of Adam's money is equal to
45 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 3 and 4.
LCM of 3 and 4 = 12
3 x 48 x 4 of Adam's money =
4 x 35 x 3 of Bryan's money
1232 of Adam's money =
1215 of Bryan's money
Amount that Adam has = 32 u
Amount that Bryan has = 15 u
32 u = 128
1 u = 128 ÷ 32 = 4
Amount that Bryan has
= 15 u
= 15 x 4
= $60
(b)
Amount that Adam has more than Bryan
= 32 u - 15 u
= 17 u
= 17 x 4
= $68
(c)
Amount that they have altogether
= 32 u + 15 u
= 47 u
= 47 x 4
= $188
Answer(s): (a) $60; (b) $68; (c) $188
