Question

A fraction is greater than by its reciprocal by (72/77). What is the fraction

Answer 1

Answer:

11/7

-7/11

Step-by-step explanation:

Let say number = N/D

then reciprocal = D/N

N/D - D/N = 72/77

N^2 - D^2 = 72DN/77

77N^2 - 77D^2 - 72DN = 0

77N^2 - 72DN - 77D^2 = 0

77N^2 - 121ND + 49ND - 77D^2 = 0

11N(7N-11D) +7D(7N-11D) = 0

(11N+7D) (7N-11D) =0

N/D = -7/11  or  11/7
