Question

Calcule:
 9,1% de R$ 50,00
 359,1% de 770 gramas 

Answer 1

$\frac{9,1}{100} = \frac{x}{50}$

$100x=9,1*50$

$100x=455$

$x= \frac{455}{100}$

$x=4,55$

$\frac{359,1}{100} = \frac{x}{770}$

$100x=359,1*770$

$100x=276.507$

$x= \frac{276.507}{100}$

$x=2765,07$


 9,1% de R$ 50,00 = R$ 4,55
 359,1% de 770 = 2765,07 gramas
