23 of Adam's money is equal to
16 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 =
16 of Bryan's money
2 x 13 x 1 of Adam's money =
1 x 26 x 2 of Bryan's money
23 of Adam's money =
212 of Bryan's money
3 u = 30
1 u = 30 ÷ 3 = 10
Amount that Bryan has
= 12 u
= 12 x 10
= $120
(b)
Amount that Bryan has more than Adam
= 12 u - 3 u
= 9 u
= 9 x 10
= $90
(c)
Amount that they have altogether
= 3 u + 12 u
= 15 u
= 15 x 10
= $150
Answer(s): (a) $120; (b) $90; (c) $150
