[tex] - 3.4 \times 2.7 = - 9.18[/tex]

[tex] - 0.45 \times ( - 2.4) = 1.08[/tex]

[tex] \frac{11}{14} \times ( - \frac{21}{44} ) = - \frac{11 \times 21}{14 \times 44} = - \frac{1 \times 3}{2 \times 4} = - \frac{3}{8} [/tex]

[tex] - 18 \div ( - 4) = 4.5[/tex]

[tex] - 24 \div ( - \frac{8}{11} ) = \frac{24 \times 11}{8} = 3 \times 11 = 33[/tex]

[tex] - 4 \frac{2}{7} \div 3 \frac{3}{14} = - \frac{30 \times 14}{7 \times 45} = - \frac{2 \times 2}{1 \times 3} = - \frac{4}{3} = - 1 \frac{1}{3} [/tex]

Пошаговое объяснение:

-3,4 * 2,7 = -(3,4 * 2,7) = -9,18

-0,45 * (-2,4) = 0,45 * 2,4 =1,08

11/14 * (-21/44) = -(11/14 * 21/44) = -(1/2 * 3/4) = -3/8

-18 : (-4) = 18 : 4 = 4,5

-24 : (-8/11) = 24 : 8/11 = 24 * 11/8 = 3 * 11/1 = 33/1 = 33

-4 2/7 : 3 3/14 = -30/7 : 45/14 = -(30/7 * 14/45) =

-(2/1 * 2/3) = -4/3 = -1 1/3
