In an office building, 42 offices are currently being rented.

This represents 40% of the total units.

Let x be the total number of offices.

Then we can write


\begin{gathered} 40\%\; of\; x=42 \\ (40)/(100)\cdot x=42 \\ 0.40\cdot x=42 \\ x=(42)/(0.40) \\ x=105 \end{gathered}

Therefore, there are 105 offices in the building.
