37 of Adam's money is equal to
13 of Bryan's money.
Adam has $70.
- How much does Bryan have?
- How much does Bryan have more than Adam?
- How much do they have altogether?
(a)
Make the numerators the same.
37 of Adam's money =
13 of Bryan's money
3 x 17 x 1 of Adam's money =
1 x 33 x 3 of Bryan's money
37 of Adam's money =
39 of Bryan's money
7 u = 70
1 u = 70 ÷ 7 = 10
Amount that Bryan has
= 9 u
= 9 x 10
= $90
(b)
Amount that Bryan has more than Adam
= 9 u - 7 u
= 2 u
= 2 x 10
= $20
(c)
Amount that they have altogether
= 7 u + 9 u
= 16 u
= 16 x 10
= $160
Answer(s): (a) $90; (b) $20; (c) $160
