To solve the problem, multiply the fractions together: $\left( \frac { 2 } { 7 } \right) \left( \frac { 4 } { 5 } \right) \left( - \frac { 5 } { 9 } \right) \left( \frac { 5 } { 8 } \right) = - \frac { 2 \cdot 4 \cdot 5 \cdot 5 } { 7 \cdot 5 \cdot 9 \cdot 8 }$. Simplifying, we get $- \frac { 200 } { 2520 } = - \frac { 5 } { 63 }$.
