45 of Adam's money is equal to
15 of Bryan's money.
Adam has $30.
- How much does Bryan have?
- How much does Adam have less than Bryan?
- How much do they have altogether?
(a)
Make the numerators the same.
45 of Adam's money =
15 of Bryan's money
4 x 15 x 1 of Adam's money =
1 x 45 x 4 of Bryan's money
45 of Adam's money =
420 of Bryan's money
5 u = 30
1 u = 30 ÷ 5 = 6
Amount that Bryan has
= 20 u
= 20 x 6
= $120
(b)
Amount that Adam has less than Bryan
= 20 u - 5 u
= 15 u
= 15 x 6
= $90
(c)
Amount that they have altogether
= 5 u + 20 u
= 25 u
= 25 x 6
= $150
Answer(s): (a) $120; (b) $90; (c) $150
