310 of Bryan's money is equal to
18 of Adam's money.
Bryan has $30.
- How much does Adam have?
- How much does Bryan have less than Adam?
- How much do they have altogether?
(a)
Make the numerators the same.
310 of Bryan's money =
18 of Adam's money
3 x 110 x 1 of Bryan's money =
1 x 38 x 3 of Adam's money
310 of Bryan's money =
324 of Adam's money
10 u = 30
1 u = 30 ÷ 10 = 3
Amount that Adam has
= 24 u
= 24 x 3
= $72
(b)
Amount that Bryan has less than Adam
= 24 u - 10 u
= 14 u
= 14 x 3
= $42
(c)
Amount that they have altogether
= 10 u + 24 u
= 34 u
= 34 x 3
= $102
Answer(s): (a) $72; (b) $42; (c) $102
