25 of Adam's money is equal to
13 of Bryan's money.
Adam has $40.
- 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.
25 of Adam's money =
13 of Bryan's money
2 x 15 x 1 of Adam's money =
1 x 23 x 2 of Bryan's money
25 of Adam's money =
26 of Bryan's money
5 u = 40
1 u = 40 ÷ 5 = 8
Amount that Bryan has
= 6 u
= 6 x 8
= $48
(b)
Amount that Bryan has more than Adam
= 6 u - 5 u
= 1 u
= 1 x 8
= $8
(c)
Amount that they have altogether
= 5 u + 6 u
= 11 u
= 11 x 8
= $88
Answer(s): (a) $48; (b) $8; (c) $88
