We have the given rational expressions: $\frac{7}{14x}$ and $\frac{7}{14+x}$ Now, simplify the first rational expression: \begin{align} & \frac{7}{14x}=\frac{7}{7\times 2\times x} \\ & =\frac{1}{2x} \end{align} Further simplify the second rational expression: $\frac{7}{14+x}$ The numerator and the denominator of the above rational expression do not have any common factors, so the above expression is already in its simplest form. So, the rational expressions $\frac{7}{14x}\ \text{ and }\ \frac{7}{14+x}$ cannot be simplified by dividing each numerator and each denominator by $7$. Thus, the given statement does not make sense.
