Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[\frac{31}{\frac{30}{}}\]
Invert and multiply.
\[31\times \frac{1}{30}\]
Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[\frac{31\times 1}{30}\]
Simplify \(31\times 1\) to \(31\).
\[\frac{31}{30}\]
Simplify.
\[\frac{31{}^{2}}{30}\]
