Question

Simplify:

\[\left( \frac{25}{8} \times \frac{2}{5} \right) - \left( \frac{3}{5} \times \frac{- 10}{9} \right)\]

Answer 1

\[(\frac{25}{8} \times \frac{2}{5}) - (\frac{3}{5} \times \frac{- 10}{9})\]
\[ = \frac{5}{4} - \frac{- 2}{3}\]
\[ = \frac{5 \times 3 + 2 \times 4}{12}\]
\[ = \frac{23}{12}\]
