Question

In ms jasmines class, 7 out of the 20 students attend an after school art program. What percent of the students attend the art program?

if we take 20 to be the 100%, what is 7 off of it in percentage?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 20&100\\ 7&x \end{array}\implies \cfrac{20}{7}=\cfrac{100}{x}\implies 20x=700\implies x=\cfrac{700}{20}\implies x=35$
