Question

Um quilograma de camarão custa R$32,00.
Quanto custa 2 3/4 kg de camarão.​

Answer 1

Explicação passo-a-passo:

=> $\sf 2~\dfrac{3}{4}=\dfrac{8+3}{4}=\dfrac{11}{4}$

Regra de 3:

$\sf ~~~quilograma~~~~~~~~~~~~valor$

$\sf ~~~~~~~~~~~1~~~~~~~~~~~~\Rightarrow~~~~~32$

$\sf ~~~~~~~~~~\dfrac{11}{4}~~~~~~~~~~\Rightarrow~~~~~~x$

$\sf x=32\cdot\dfrac{11}{4}$

$\sf x=\dfrac{32\cdot11}{4}$

$\sf x=\dfrac{352}{4}$

$\sf \red{x=88~reais}$
