38 of Adam's money is equal to
15 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.
38 of Adam's money =
15 of Bryan's money
3 x 18 x 1 of Adam's money =
1 x 35 x 3 of Bryan's money
38 of Adam's money =
315 of Bryan's money
8 u = 40
1 u = 40 ÷ 8 = 5
Amount that Bryan has
= 15 u
= 15 x 5
= $75
(b)
Amount that Bryan has more than Adam
= 15 u - 8 u
= 7 u
= 7 x 5
= $35
(c)
Amount that they have altogether
= 8 u + 15 u
= 23 u
= 23 x 5
= $115
Answer(s): (a) $75; (b) $35; (c) $115
