$\frac{10 f + 6}{f}$

#### Explanation:

Given: $10 + \frac{6}{f}$

A rational expression is an expression with a numerator and denominator that are polynomials: $\frac{N \left(x\right)}{D \left(x\right)}$

For the given expression, find a common denominator:

$10 \cdot \frac{f}{f} + \frac{6}{f} = \frac{10 f}{f} + \frac{6}{f} = \frac{10 f + 6}{f}$
