Question 353501: if one is added to a fraction and then the result is inverted and subtracted from the fraction, the difference is 1/15. what is the original fraction? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! Let the fraction be x.
x+1
x - 1/(x+1) = 1/15
15x(x+1)-15=x+1
15x^2+15x-15=x+1
15x^2+14x-16=0
x=-8/5, x=2/3 Quadratic formula.
