23 of Adam's money is equal to
49 of Bryan's money.
Adam has $30.
- 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.
23 of Adam's money =
49 of Bryan's money
2 x 23 x 2 of Adam's money =
4 x 19 x 1 of Bryan's money
46 of Adam's money =
49 of Bryan's money
6 u = 30
1 u = 30 ÷ 6 = 5
Amount that Bryan has
= 9 u
= 9 x 5
= $45
(b)
Amount that Bryan has more than Adam
= 9 u - 6 u
= 3 u
= 3 x 5
= $15
(c)
Amount that they have altogether
= 6 u + 9 u
= 15 u
= 15 x 5
= $75
Answer(s): (a) $45; (b) $15; (c) $75
