If it is the reciprocal of x minus 5 than 1/x-5>1/3x
The reciprocal of any positive integer x is equal to 1/x. Therefore, the reciprocal of 8 is equal to 1/8 or one eighth.

Apply the reciprocal rule: If f(x) = 1/h(x) then f'(x) = -h'(x)/(h(x))^2
Number x Reciprocal = 1 Therefore Reciprocal = 1/Number
