Question

13% of the 800 runners in a marathon were women. How many women ran the marathon?

Answer 1

Solution

- The formula for the percentage of women is:

$\begin{gathered} \%\text{ Women}=\frac{Number\text{ of women\lparen n\rparen}}{Total\text{ number of people}}\times100\% \\ \\ 13\%=\frac{n}{800}\times100\% \\ \\ 13=\frac{n}{8} \\ \\ n=13\times8 \\ \\ n=104 \end{gathered}$

Final Answer

The answer is 104
