Solution

We know, $Product of two rational numbers = \frac{Product of their numerators}{Product of their denominators}$
So, $\frac{- 5}{8} \times \frac{4}{9}$
$= \frac{- 5 \times 4}{8 \times 9} = \frac{- 5 \times 4}{\underset{2}{8} \times 9} = \frac{- 5}{2 \times 9} = \frac{- 5}{18}$
Hence, $\frac{- 5}{8} \times \frac{4}{9} = \frac{- 5}{18}$ .
