45 of Adam's money is equal to
12 of Bryan's money.
Adam has $70.
- 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 =
12 of Bryan's money
4 x 15 x 1 of Adam's money =
1 x 42 x 4 of Bryan's money
45 of Adam's money =
48 of Bryan's money
5 u = 70
1 u = 70 ÷ 5 = 14
Amount that Bryan has
= 8 u
= 8 x 14
= $112
(b)
Amount that Adam has less than Bryan
= 8 u - 5 u
= 3 u
= 3 x 14
= $42
(c)
Amount that they have altogether
= 5 u + 8 u
= 13 u
= 13 x 14
= $182
Answer(s): (a) $112; (b) $42; (c) $182
