Verified answer

Пошаговое объяснение:

1)

[tex] - 6.2 \times 3.4 = - (6.2 \times 3.4) = - 21.08[/tex]

2)

[tex] - 6 \frac{3}{4} \times ( - 1 \frac{11}{45} ) = - \frac{27}{4} \times ( - \frac{56}{45} ) = 27 \times \frac{14}{45} = 3 \times \frac{14}{5} = \frac{42}{5} = 8 \frac{2}{5} = 8.4[/tex]

3)

[tex] - 19.68 \div ( - 0.8) = 19.68 \div 0.8 = 24.6[/tex]

4)

[tex]16.32 \div ( - 16) = - (16.32 \div 16) = - 1.02[/tex]
