Accepted Answer

Para calcular os percentuais, use a fórmula:

$$
\text{Porcentagem} = \left(\frac{\text{percentual}}{100}\right) \times \text{valor}
$$

a) $30\% \text{ de } 1500 = \left(\frac{30}{100}\right) \times 1500 = 450$

b) $12\% \text{ de } 120 = \left(\frac{12}{100}\right) \times 120 = 14,4$

c) $27\% \text{ de } 900 = \left(\frac{27}{100}\right) \times 900 = 243$

d) $55\% \text{ de } 300 = \left(\frac{55}{100}\right) \times 300 = 165$

e) $98\% \text{ de } 450 = \left(\frac{98}{100}\right) \times 450 = 441$
