Question

With 400,000 sq ft or 16% of total office space. How much space did the city have

Answer 1

If 400,000 is 16%, and "x" is say the 100%

well then    $\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 400,000&16\\ x&100 \end{array}\implies \cfrac{400000}{x}=\cfrac{16}{100}$

solve for "x".
