[tex]3 \frac{6}{7} \times ( - \frac{1}{3} ) = \frac{27}{7} \times ( - \frac{1}{3} ) = ( - \frac{9}{3}) \times ( - \frac{1}{1}) = ( - \frac{9}{3} )=( - 3) \\ ( - 2 \frac{2}{9} ) \times ( - 1.17) = ( - \frac{20}{9} ) \times ( - \frac{117}{100} ) = \frac{1}{9} \times \frac{117}{5} = \frac{117}{45} = 2 \frac{27}{45} = 2 \frac{3}{5} [/tex]
