Question

Resolva:

h) $\frac{1}{4}$ + 0,19 : (4 - 0,8 : 0,5 - $\frac{1}{2}$ )

Answer 1

$\frac{1}{4} + 0.19 \div (4 - 0.8 \div 0.5 - \frac{1}{2} ) \\ \\ \frac{1}{4} + \frac{19}{100} \div (4 - 1.6 - \frac{1}{2} ) \\ \\ \frac{1}{4} + \frac{19}{100} \div (4 - \frac{8}{5} - \frac{1}{2} ) \\ \\ \frac{1}{4} + \frac{19}{100} \times \frac{10}{19} \\ \\ \frac{1}{4} + \frac{1}{10} \\ \\ \frac{7}{20}$

Ou 0.35.
