19 of Adam's money is equal to
45 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 1 and 4.
LCM of 1 and 4 = 4
1 x 49 x 4 of Adam's money =
4 x 15 x 1 of Bryan's money
436 of Adam's money =
45 of Bryan's money
Amount that Adam has = 36 u
Amount that Bryan has = 5 u
36 u = 216
1 u = 216 ÷ 36 = 6
Amount that Bryan has
= 5 u
= 5 x 6
= $30
(b)
Amount that Adam has more than Bryan
= 36 u - 5 u
= 31 u
= 31 x 6
= $186
(c)
Amount that they have altogether
= 36 u + 5 u
= 41 u
= 41 x 6
= $246
Answer(s): (a) $30; (b) $186; (c) $246
