310 of Adam's money is equal to
15 of Bryan's money.
Adam has $50.
- 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 =
15 of Bryan's money
3 x 110 x 1 of Adam's money =
1 x 35 x 3 of Bryan's money
310 of Adam's money =
315 of Bryan's money
10 u = 50
1 u = 50 ÷ 10 = 5
Amount that Bryan has
= 15 u
= 15 x 5
= $75
(b)
Amount that Adam has less than Bryan
= 15 u - 10 u
= 5 u
= 5 x 5
= $25
(c)
Amount that they have altogether
= 10 u + 15 u
= 25 u
= 25 x 5
= $125
Answer(s): (a) $75; (b) $25; (c) $125
