310 of Adam's money is equal to
111 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.
310 of Adam's money =
111 of Bryan's money
3 x 110 x 1 of Adam's money =
1 x 311 x 3 of Bryan's money
310 of Adam's money =
333 of Bryan's money
10 u = 20
1 u = 20 ÷ 10 = 2
Amount that Bryan has
= 33 u
= 33 x 2
= $66
(b)
Amount that Adam has less than Bryan
= 33 u - 10 u
= 23 u
= 23 x 2
= $46
(c)
Amount that they have altogether
= 10 u + 33 u
= 43 u
= 43 x 2
= $86
Answer(s): (a) $66; (b) $46; (c) $86
