$\frac{6 \times 3 \times ( - 0.2) {}^{2} }{9 - 81 \times 0.2 {}^{2} } \times \frac{3 + 1.8}{3 \times ( - 0.2)} \\ \frac{6 \times 3 \times ( - 0.2) {}^{2} }{9 - 81( \frac{1}{5}) {}^{2} } \times \frac{4.8}{3 \times ( - 0.2)} \\ \frac{6 \times 3 \times ( - .02) {}^{2} }{9 - \frac{81}{25} } \times \frac{4.8}{3 \times ( - 0.2)} \\ \frac{6 \times 3 \times ( - 0.2) {}^{2} }{ \frac{144}{25} } \times \frac{4.8}{3 \times ( - 0.2)} \\ \frac{25 \times ( - 0.2) {}^{2} }{8} \times \frac{4.8}{3 \times ( - 0.2)} \\ \frac{25 \times 0.2 {}^{2} }{8} \times \frac{4.8}{3 \times ( - 0.2)} \\ - \frac{25 \times 0.2}{8} \times \frac{4.8}{3} \\ \frac{28 \times \frac{1}{5} }{8} \times 1.6 \\ - \frac{5}{8} \times \frac{8}{5} = - 1$
