Answer 1

Resposta:

$\frac { - 1}{20}$

$\frac{1}{2} - \frac{8}{10} + \frac{3}{4} - \sqrt{ \frac{1}{4} }$

$\frac{1}{2} - \frac{8 \div 2}{10 \div 2} + \frac{3}{4} - \frac{ \sqrt{1} }{\sqrt{4} }$

$\frac{1}{2} - \frac{4}{5} + \frac{3}{4} - \frac{1}{2}$

$\frac{1}{2} - \frac{1}{2} - \frac{4}{5} + \frac{3}{4}$

$- \frac{4}{5} + \frac{3}{4}$

$\frac{ - 16 + 15}{20}$

$\frac { - 1}{20}$
