Step-by-step explanation:

$(( { \frac{3}{4} )}^{ - 2} \div ( { \frac{4}{5} )}^{ - 3} ) \times {( \frac{3}{5} )}^{ - 2} \\ \\ = > ({( \frac{4}{3} )}^{2} \div {( \frac{5}{4} )}^{3} ) \times {( \frac{5}{3} )}^{2} \\ \\ = > ({( \frac{4}{3} )}^{2} \times { (\frac{4}{5} )}^{3} ) \times { (\frac{5}{3} )}^{2} \\ \\ = > \frac{4 \times 4 \times 4 \times 4 \times 4}{3 \times 3 \times 5 \times 5 \times 5} \times \frac{5 \times 5}{3 \times 3} \\ \\ = > \frac{1024}{405}$
