Question

Um carro consumiu 75 litros de álcool para percorrer 975 km. Supondo as mesmas condições, quanto esse mesmo carro consumirá para percorrer 1 105 km?

Answer 1

$\Large\displaystyle\text{ \begin{gathered} \sf{\frac{75\,L}{x\,L}=\frac{975\,km}{1105\,km} } \end{gathered} }$

$\Large\displaystyle\begin{gathered} \sf{ 975x=1105\cdot75} \end{gathered}$

$\Large\displaystyle\begin{gathered} \sf{975x=82875 } \end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \sf{ x=\frac{82875}{975}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\sf{x=85\,L}}} \end{gathered} }$
