Answer 1

$(6.75 - 4.5 \times 1 \times \frac{2}{3} ) \times ( - 1 \times \frac{1}{3} ) { {}^{} }^{3} = - 5 \\ (6.75 - \frac{9}{2} \times \frac{2}{3} ) \times ( - \frac{4}{5} ) \\ (6.75 - 3) \times ( - \frac{4}{3} ) \\ 3.75 \times ( - \frac{4}{3} ) \\ \frac{15}{4} \times ( - \frac{4}{3} ) \\ = - 5$

${?}^{2} c)( - \frac{11}{18} + ( - 2 \frac{3}{9} ) \times ( - 0.2)) {}^{3} \times ( - 1.2) \\ ( - \frac{11}{18} + ( - \frac{21}{9} ) \times ( - \frac{1}{5} ) {)}^{3} \times ( - 1.2) \\ ( - \frac{11}{18} + \frac{7}{3} \times \frac{1}{5} {)}^{3} \times ( - 1.2) \\ ( - \frac{11}{18} + \frac{7}{15} {)}^{3} \times ( - 1.2) \\ ( - \frac{13}{90} {)}^{3}( - 1.2) \\ \\ \frac{13 {}^{3} }{90 {}^{3} } \times \frac{6}{5} \\ \frac{6 \times 13 {}^{3} }{5 \times 90 {}^{3} } \\ \frac{6 \times 2197}{5 \times 90 {}^{3} } \\ \frac{13182}{5 \times 90 {}^{3} }$
