​

Answer 1

$\frak{ \large \frac{3}{4} + \bigg( \frac{ - 2}{5} \bigg) + \bigg(\frac{ - 7}{10} \bigg) + \frac{5}{8}} \\ \\ \leadsto \: \: \frac{3}{4} - \frac{2}{5} - \frac{7}{10} + \frac{5}{8} \\ \\ \leadsto \: \: \frac{30 - 16 - 28 + 25}{40} \\ \\ \leadsto \: \: \frac{55 - 44}{40} \: \: \: \: = \red{\frac{11}{40}}$
