Question

1. The difference between a positive fraction and 1 point
its reciprocal is 920. Find the sum of that
fraction and its reciprocal.​

Answer 1

Answer:

Let x be the required fraction then acc to Q we have, 1/x - x = 9/20

So, (1-x^2)/x = 9/20

20 - 20x^2 =9x

20x^2 + 9x - 20 = 0

20x^2 - 25x-16x - 20 = 0

5x(4x+5)-4(4x+5) = 0

(5x-4) (4x+5) = 0

 Hence,x = 4/5
