Oksi-84 [34.3K]

Answer:

Option B is the correct answer

Step-by-step explanation:

The exact expression is:

$\frac{\frac{1}{4n}-\frac{1}{2}}{\frac{n}{6}-\frac{1}{24n} }$

Taking LCM in numerator and denominator can simplify the expression. Further simplifying the expression can give us the final result, as shown below:

$\frac{\frac{1-2n}{4n} }{\frac{4n^{2}-1 }{24n}} \\\\=\frac{1-2n}{4n}\times\frac{24n}{4n^{2}-1 }\\\\=\frac{1-2n}{4n}\times\frac{24n}{(2n+1)(2n-1)}\\\\ =-\frac{2n-1}{4n}\times\frac{24n}{(2n+1)(2n-1)}\\\\ =-\frac{6}{2n+1}$
