12 of Bryan's money is equal to
45 of Adam's money.
Bryan has $152.
- 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 4.
LCM of 1 and 4 = 4
1 x 42 x 4 of Bryan's money =
4 x 15 x 1 of Adam's money
48 of Bryan's money =
45 of Adam's money
Amount that Bryan has = 8 u
Amount that Adam has = 5 u
8 u = 152
1 u = 152 ÷ 8 = 19
Amount that Adam has
= 5 u
= 5 x 19
= $95
(b)
Amount that Bryan has more than Adam
= 8 u - 5 u
= 3 u
= 3 x 19
= $57
(c)
Amount that they have altogether
= 8 u + 5 u
= 13 u
= 13 x 19
= $247
Answer(s): (a) $95; (b) $57; (c) $247
