Which expression is equivalent to mn²/mn+m²n² ? a.) 1/n+m b.) n/1+m²n² c.) n/1+mn d.) 1/m²n​
ozzi

<u>Given</u>:

The given expression is \frac{m n^{2}}{m n+m^{2} n^{2}}

We need to determine the equivalent expression.

<u>Equivalent expression:</u>

The equivalent expression can be determined by simplifying the given expression.

Thus, let us factor out the common term "mn" from the denominator.

Thus, we have;

\frac{m n^{2}}{n m(1+m n)}

Cancelling the common terms, we get;

\frac{n}{1+m n}

Thus, the equivalent expression is \frac{n}{1+m n}

Hence, Option c is the correct answer.
