Question

se trinta e dois litros de um combustivel custam 164,80 quantos custam quarenta e cinco listros do mesmo combustível? ​

Answer 1

Dados:

32L= 164,80

164,80/32= 5,15

1L= 5,15

45L= 5,15x45= 231,75

Answer 2

   ☞ Custarão R$231,75 em combustível.

Nesse problema,utilizamos a regra de 3 simples.

Montamos o quadro:

$\large\green{\boxed{\red{\boxed{\tt\orange{\begin{array}{c|c}\underline{\sf LITROS }&\underline{\sf R\ }\\\sf32&\sf164{,}80\\\sf45&\sf X \end{array}}}}}}$

$\bf\large{\underline{\quad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\quad}}$✍

Agora fazemos os cálculos:

$\large\red{\boxed{\purple{\boxed{\begin{array}{l} \large \sf 32X=45.164{,}80 \\ \\ \large \sf 32X=7416 \\ \\ \large \sf x=\dfrac{7416}{32} \\ \\ \large \sf x=231{,}75 \end{array}}}}}$

$\bf\large{\underline{\quad\qquad\qquad\qquad\qquad\qquad\qquad\qquad\quad}}$✍

No total serão R$231,75
