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?

Answer 1

35%

Explanation:

To answer this question, I'd form the ratio 7/20 and then multiply the result by 100%:

(7/20)(100%) = 35% (answer)

Answer 2

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`
