910 of Adam's money is equal to
79 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.
910 of Adam's money =
79 of Bryan's money
9 x 710 x 7 of Adam's money =
7 x 99 x 9 of Bryan's money
6370 of Adam's money =
6381 of Bryan's money
70 u = 70
1 u = 70 ÷ 70 = 1
Amount that Bryan has
= 81 u
= 81 x 1
= $81
(b)
Amount that Adam has less than Bryan
= 81 u - 70 u
= 11 u
= 11 x 1
= $11
(c)
Amount that they have altogether
= 70 u + 81 u
= 151 u
= 151 x 1
= $151
Answer(s): (a) $81; (b) $11; (c) $151
