Answer :
if we take 62,400 to be the 100%, what is 9,860 in percentage off of it?
[tex]\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 62400&100\\ 9860&x \end{array}\implies \cfrac{62400}{9860}=\cfrac{100}{x}[/tex]
solve for "x".
