उत्तर
\[(\frac{- 4}{3} \times \frac{12}{- 5}) + (\frac{3}{7} \times \frac{21}{15})\]
\[ = \frac{4 \times 4}{5} + \frac{1 \times 3}{5}\]
\[ = \frac{16}{5} + \frac{3}{5}\]
\[ = \frac{16 + 3}{5}\]
\[ = \frac{19}{5}\]

Re-arrange suitably and find the sum in each of the following:
\[\frac{1}{8} + \frac{5}{12} + \frac{2}{7} + \frac{7}{12} + \frac{9}{7} + \frac{- 5}{16}\]
Simplify:
\[\frac{- 2}{5} - \frac{- 3}{10} - \frac{- 4}{7}\]
Simplify:
\[\frac{3}{8} - \frac{- 2}{9} + \frac{- 5}{36}\]
Simplify:
\[\left( \frac{1}{2} \times \frac{1}{4} \right) + \left( \frac{1}{2} \times 6 \right)\]
Simplify:
\[\left( - 5 \times \frac{2}{15} \right) - \left( - 6 \times \frac{2}{9} \right)\]
Simplify:
\[\left( \frac{- 9}{4} \times \frac{5}{3} \right) + \left( \frac{13}{2} \times \frac{5}{6} \right)\]
