Solution

We know, $Product of two rational numbers = \frac{Product of their numerators}{Product of their denominators}$
So, $\frac{3}{8} \times \frac{- 5}{7} \times \frac{7}{9}$
$= \frac{3 \times (- 5) \times 7}{8 \times 7 \times 9} = \frac{3 \times (- 5) \times 7}{8 \times 7 \times 9} = \frac{3 \times - 5}{8 \times \underset{3}{9}} = \frac{- 5}{8 \times 3} = \frac{- 5}{24}$
Hence, $\frac{3}{8} \times \frac{- 5}{7} \times \frac{7}{9} = \frac{- 5}{24}$ .
