38 of Adam's money is equal to
12 of Bryan's money.
Adam has $216.
- 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 1.
LCM of 3 and 1 = 3
3 x 18 x 1 of Adam's money =
1 x 32 x 3 of Bryan's money
38 of Adam's money =
36 of Bryan's money
Amount that Adam has = 8 u
Amount that Bryan has = 6 u
8 u = 216
1 u = 216 ÷ 8 = 27
Amount that Bryan has
= 6 u
= 6 x 27
= $162
(b)
Amount that Adam has more than Bryan
= 8 u - 6 u
= 2 u
= 2 x 27
= $54
(c)
Amount that they have altogether
= 8 u + 6 u
= 14 u
= 14 x 27
= $378
Answer(s): (a) $162; (b) $54; (c) $378
