13 of Adam's money is equal to
710 of Bryan's money.
Adam has $105.
- 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 7.
LCM of 1 and 7 = 7
1 x 73 x 7 of Adam's money =
7 x 110 x 1 of Bryan's money
721 of Adam's money =
710 of Bryan's money
Amount that Adam has = 21 u
Amount that Bryan has = 10 u
21 u = 105
1 u = 105 ÷ 21 = 5
Amount that Bryan has
= 10 u
= 10 x 5
= $50
(b)
Amount that Adam has more than Bryan
= 21 u - 10 u
= 11 u
= 11 x 5
= $55
(c)
Amount that they have altogether
= 21 u + 10 u
= 31 u
= 31 x 5
= $155
Answer(s): (a) $50; (b) $55; (c) $155
