<em>85% of the students in Yvan’s school walk to school. If 816 students walk to school, how many students are in the school?</em>

<em>Response-</em>

Since we are using percents we can make an equation out of this question

\frac{85}{100}=\frac{816}{x}

\frac{85}{100} is the way we write percents in math as a fraction

and \frac{816}{x} is the part and whole you gave us

\frac{85}{100}=\frac{816}{x} cross multiply

85x=81600\\divide\\x=960students are in the school
