710 of Adam's money is equal to
13 of Bryan's money.
Adam has $20.
- How much does Bryan have?
- How much does Adam have less than Bryan?
- How much do they have altogether?
(a)
Make the numerators the same.
710 of Adam's money =
13 of Bryan's money
7 x 110 x 1 of Adam's money =
1 x 73 x 7 of Bryan's money
710 of Adam's money =
721 of Bryan's money
10 u = 20
1 u = 20 ÷ 10 = 2
Amount that Bryan has
= 21 u
= 21 x 2
= $42
(b)
Amount that Adam has less than Bryan
= 21 u - 10 u
= 11 u
= 11 x 2
= $22
(c)
Amount that they have altogether
= 10 u + 21 u
= 31 u
= 31 x 2
= $62
Answer(s): (a) $42; (b) $22; (c) $62
