Answer 1

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