Answer 1

Resposta:

10% de 65

$10\% = \frac{10}{100} = \frac{1}{10}$

$10\% \: de \: 65 = \frac{1}{10} \times 65 = \frac{65}{10} = 6.5$

-------------------------------------------------

13% de 78

$13\% = \frac{13}{100}$

$13\% \: de \: 78 = \frac{13}{100} \times 78 = \frac{1014}{100}$

$\frac{1014}{100} = 10.14$

-------------------------------------------------

9% de 120

$9\% = \frac{9}{100}$

$9\% \: de \: 120 = \frac{9}{100} \times 120 = \frac{1080}{100}$

$\frac{1080}{100} = 10.8$

-------------------------------------------------

47% de 250

$47\% = \frac{47}{100}$

$47\% \: de \: 250 = \frac{45}{100} \times 250 = \frac{11250}{100}$

$\frac{11250}{100} = 112.5$

-------------------------------------------------

90% de 1500

$90\% = \frac{90}{100} = \frac{9}{10}$

$90\% \: de \: 1500 = \frac{9}{10} \times 1500 = \frac{13500}{10}$

$\frac{13500}{10} = 1350$
