COMPLETE Evaluate ((m)/(n))(x) for x=-3 (m)/(n)(-3)=

To evaluate the expression $(\frac {m}{n})(x)$ for $x=-3$, we need to substitute $x$ with $-3$ and then simplify the expression.<br /><br />Given expression: $(\frac {m}{n})(x)$<br /><br />Substitute $x$ with $-3$:<br />$(\frac {m}{n})(-3)$<br /><br />To simplify this expression, we need to multiply the fraction $\frac {m}{n}$ by $-3$.<br /><br />$(\frac {m}{n})(-3) = \frac {m(-3)}{n} = \frac {-3m}{n}$<br /><br />Therefore, the evaluated expression is $\frac {-3m}{n}$.
