45 of Adam's money is equal to
811 of Bryan's money.
Adam has $90.
- 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 =
811 of Bryan's money
4 x 25 x 2 of Adam's money =
8 x 111 x 1 of Bryan's money
810 of Adam's money =
811 of Bryan's money
10 u = 90
1 u = 90 ÷ 10 = 9
Amount that Bryan has
= 11 u
= 11 x 9
= $99
(b)
Amount that Adam has less than Bryan
= 11 u - 10 u
= 1 u
= 1 x 9
= $9
(c)
Amount that they have altogether
= 10 u + 11 u
= 21 u
= 21 x 9
= $189
Answer(s): (a) $99; (b) $9; (c) $189
