Answer 1

if we take 64 as the 100%, what is 8 of 64 in percentage then?

well
`\bf \begin{array}{ccllll} amount&\%\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 64&100\\ 8&x \end{array}\implies \cfrac{64}{8}=\cfrac{100}{x}`

solve for "x"
