12 of Adam's money is equal to
45 of Bryan's money.
Adam has $112.
- 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 42 x 4 of Adam's money =
4 x 15 x 1 of Bryan's money
48 of Adam's money =
45 of Bryan's money
Amount that Adam has = 8 u
Amount that Bryan has = 5 u
8 u = 112
1 u = 112 ÷ 8 = 14
Amount that Bryan has
= 5 u
= 5 x 14
= $70
(b)
Amount that Adam has more than Bryan
= 8 u - 5 u
= 3 u
= 3 x 14
= $42
(c)
Amount that they have altogether
= 8 u + 5 u
= 13 u
= 13 x 14
= $182
Answer(s): (a) $70; (b) $42; (c) $182
