On a particular Saturday, 60% of the visitors at an art museum were students. If 150 students visited the museum, how many total visitors did the art museum have that day?
well, the total amount of visitors were "x", which is 100%
now, we know that 150 students, or 150, is 60% of that "x",
so, what's "x"? or the 100%?
well \(\bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
150&60\\
x&100
\end{array}\implies \cfrac{150}{x}=\cfrac{60}{100}\)
solve for "x"
60% of total visitors = 150
100% visitors = \(150 \times \frac{100}{60} = \boxed{250}\)
