12 of Adam's money is equal to
512 of Bryan's money.
Adam has $30.
- 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.
12 of Adam's money =
512 of Bryan's money
1 x 52 x 5 of Adam's money =
5 x 112 x 1 of Bryan's money
510 of Adam's money =
512 of Bryan's money
10 u = 30
1 u = 30 ÷ 10 = 3
Amount that Bryan has
= 12 u
= 12 x 3
= $36
(b)
Amount that Adam has less than Bryan
= 12 u - 10 u
= 2 u
= 2 x 3
= $6
(c)
Amount that they have altogether
= 10 u + 12 u
= 22 u
= 22 x 3
= $66
Answer(s): (a) $36; (b) $6; (c) $66
