23 of Adam's money is equal to
18 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 =
18 of Bryan's money
2 x 13 x 1 of Adam's money =
1 x 28 x 2 of Bryan's money
23 of Adam's money =
216 of Bryan's money
3 u = 30
1 u = 30 ÷ 3 = 10
Amount that Bryan has
= 16 u
= 16 x 10
= $160
(b)
Amount that Bryan has more than Adam
= 16 u - 3 u
= 13 u
= 13 x 10
= $130
(c)
Amount that they have altogether
= 3 u + 16 u
= 19 u
= 19 x 10
= $190
Answer(s): (a) $160; (b) $130; (c) $190
