Answer 1

$34 \times ( - 4) = - 136$

$- 7.2 \times ( - 7 )= 50.4$

$- 3 \frac{1}{5} \times 1\frac{2}{3} = - \frac{16 \times 5}{5 \times 3 } = - \frac{16}{3} = - 5 \frac{1}{3}$

$- 3 \frac{5}{9} \times ( - 1 \frac{1}{8} ) = \frac{32 \times 9}{9 \times 8} = \frac{32}{8} = 4$

$- 14.3 \times 0.6 + 5.7 \times ( - 1.4) = - 8.58 - 7.98 = - 16.56$

$(3.4 - 5) \times ( - 4.12 + 4.04) = - 1.6 \times ( - 0.08) = 0.128$

$\frac{5}{9} \times ( - 3 \frac{6}{7} ) - ( - 3 \frac{5}{7} )\times \frac{3}{52} = - \frac{5 \times 27}{9 \times 7} + \frac{26 \times 3}{7 \times 52} = - \frac{5 \times 3}{7} + \frac{3}{7 \times 2} = - \frac{30}{14} + \frac{3}{14} = - \frac{27}{14} = - 1 \frac{13}{14}$

$(2 \frac{1}{3} - 3 \frac{1}{4} ) \times (2 \frac{3}{4} - 0.95) = ( \frac{7}{3} - \frac{13}{4} ) \times (2.75 - 0.95) = ( \frac{28}{12} - \frac{39}{12} ) \times 1.8 = - \frac{11}{12} \times \frac{9}{5} = - \frac{33}{20} = - 1.65$
