Answer 1

Hey friend,
Here is the answer you were looking for:
$\frac{3}{4} + ( - \frac{2}{5} + ( - \frac{7}{10} )) = ( \frac{3}{4} + ( - \frac{2}{5} )) + ( - \frac{7}{10} ) \\ \\ \\ \frac{3}{4} + ( - \frac{2}{5} - \frac{7}{10} ) = ( \frac{3}{4} - \frac{2}{5} ) - \frac{7}{10} \\ \\ \\ \frac{3}{4} + ( \frac{ - 2 \times 2 - 7 \times 1}{10} ) = ( \frac{3 \times 5 - 2 \times 4}{20} ) - \frac{7}{10} \\ \\ \\ \frac{3}{4} + ( \frac{ - 4 - 7}{10} ) = ( \frac{15 - 8}{20} ) - \frac{7}{10} \\ \\ \\ \frac{3}{4} + ( - \frac{11}{10} ) = \frac{7}{20} - \frac{7}{10} \\ \\ \\ \frac{3}{4} - \frac{11}{10} = \frac{7 \times 1 - 7 \times 2}{20} \\ \\ \\ \frac{3 \times 5 - 11 \times 2}{20} = \frac{7 - 14}{20} \\ \\ \\ \frac{15 - 22}{20} = \frac{ - 7}{20} \\ \\ \\ \frac{ - 7}{20} = \frac{ - 7}{20}$

Hence verified.
