\frac{v}{\frac{5\times 6}{6}+\frac{w}{6}}
To add or subtract expressions, expand them to make their denominators the same. Multiply 5 times \frac{6}{6}.
\frac{v}{\frac{5\times 6+w}{6}}
Since \frac{5\times 6}{6} and \frac{w}{6} have the same denominator, add them by adding their numerators.
\frac{v}{\frac{30+w}{6}}
Do the multiplications in 5\times 6+w.
\frac{v\times 6}{30+w}
Divide v by \frac{30+w}{6} by multiplying v by the reciprocal of \frac{30+w}{6}.
