12 of Adam's money is equal to
27 of Bryan's money.
Adam has $20.
- 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.
12 of Adam's money =
27 of Bryan's money
1 x 22 x 2 of Adam's money =
2 x 17 x 1 of Bryan's money
24 of Adam's money =
27 of Bryan's money
4 u = 20
1 u = 20 ÷ 4 = 5
Amount that Bryan has
= 7 u
= 7 x 5
= $35
(b)
Amount that Bryan has more than Adam
= 7 u - 4 u
= 3 u
= 3 x 5
= $15
(c)
Amount that they have altogether
= 4 u + 7 u
= 11 u
= 11 x 5
= $55
Answer(s): (a) $35; (b) $15; (c) $55
