Answer 1

${( \frac{3}{ {5}^{ - 1} }) }^{ - 2} \times { (\frac{10}{15} )}^{ - 3} \times {( \frac{1}{6} )}^{ - 1} \\ \\ = {(3 \times 5)}^{ - 2} \times { (\frac{15}{10}) }^{3} \times 6 \\ \\ = \frac{1}{15 \times 15} \times \frac{15 \times 15 \times 15}{10 \times 10 \times 10} \times 6 \\ \\ = \frac{15 \times 6}{1000 } \\ \\ = \frac{90}{1000} \\ \\ = \frac{9}{100} \\ \\ = 0.09$
