Question

28. The difference between two

numbers is 80. If the ratio of two
numbers is 3:5, find the
numbers *​

Answer 1

We set up 2 equations:

n - m = 80 so "n" is the larger number

A) n - m = 80

B) m / n = .6

A) n = 80 + m

B) m = .6 n so B) n = (5/3) m

We substitute B) into A)

(5/3) m = 80 + m

(2/3) m = 80

m = 1.5 * 80

m = 120

n = 200
