Question

800g custa 13.00 quanto custaria 1kg​

Answer 1

Resposta:

Sabe-se que,

$1\ \text{kg} = 1000 \ \text{g}$

Então, se

$800\ \text{g}=\text{R}\ \ 13,00\\1000\ \text{g}=\text{R}\ \ x$

Aplicando a regra de três,

$800x=1000\cdot \text{R}\ \ 13,00\\800x=\text{R}\ \ 13000,00$

$x=\dfrac{\text{R}\ \ 13000,00}{800}$

$x=\text{R}\ \ 16,25$
