15 of Bryan's money is equal to
23 of Adam's money.
Bryan has $100.
- 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 2.
LCM of 1 and 2 = 2
1 x 25 x 2 of Bryan's money =
2 x 13 x 1 of Adam's money
210 of Bryan's money =
23 of Adam's money
Amount that Bryan has = 10 u
Amount that Adam has = 3 u
10 u = 100
1 u = 100 ÷ 10 = 10
Amount that Adam has
= 3 u
= 3 x 10
= $30
(b)
Amount that Bryan has more than Adam
= 10 u - 3 u
= 7 u
= 7 x 10
= $70
(c)
Amount that they have altogether
= 10 u + 3 u
= 13 u
= 13 x 10
= $130
Answer(s): (a) $30; (b) $70; (c) $130
