12 of Adam's money is equal to
411 of Bryan's money.
Adam has $80.
- 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.
12 of Adam's money =
411 of Bryan's money
1 x 42 x 4 of Adam's money =
4 x 111 x 1 of Bryan's money
48 of Adam's money =
411 of Bryan's money
8 u = 80
1 u = 80 ÷ 8 = 10
Amount that Bryan has
= 11 u
= 11 x 10
= $110
(b)
Amount that Adam has less than Bryan
= 11 u - 8 u
= 3 u
= 3 x 10
= $30
(c)
Amount that they have altogether
= 8 u + 11 u
= 19 u
= 19 x 10
= $190
Answer(s): (a) $110; (b) $30; (c) $190
