\begin{array}ll \cline{1-1} \textit{\textit{\LARGE a}\% of \textit{\LARGE b}}\\ \cline{1-1} \\ \left( \cfrac{\textit{\LARGE a}}{100} \right)\cdot \textit{\LARGE b} \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{15\% of 40}}{\left( \cfrac{15}{100} \right)40}\implies \text{\LARGE 6}

She has dug 6 holes.
10% of 40 is 4
5% of 40 is 2.
4 + 2 = 6
