faça essa questão na forma fracionaria
-1/2-[5-(+5/2-0,3)]

Answer 1

$- \frac{1}{2} - ( \frac{5}{1} ( \frac{5}{2} - \frac{3}{10} )) \\ \\ - \frac{1}{2} - ( \frac{5}{1} ( \frac{25}{10} - \frac{3}{10} )) \\ \\ \\ - \frac{1}{2} - ( \frac{5}{1} \times \frac{22}{10} ) \\ \\ - \frac{1}{2} - ( \frac{110}{10} ) \\ \\ - \frac{1}{2} - \frac{110 \div 5}{10 \div 5} \\ \\ - \frac{1}{2} - \frac{22}{2} \\ \\ - \frac{23}{2}$
