asked • 10/26/18The numerator of a fraction is 15 less than its denominator. If the sum of the numerator and denominator is 79, what is the fraction.
How do I figure this out?!

x = the denominator
x - 15 = the numerator
Then
x + (x + 15) = 79
Solve for x, and then plug it into (x - 15)/x to get the fraction.
