Respuesta :

if we take 401 to be the 100%, what is 21 off of it in percentage?

[tex]\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 401&100\\ 21&p \end{array}\implies \cfrac{401}{21}=\cfrac{100}{p}\implies p=\cfrac{21\cdot 100}{401}[/tex]
