Answer 1

Пошаговое объяснение:

$- 7.2 \times 2 \frac{2}{15} - 7.2 \times 3 \frac{7}{15} - 7.2 \times ( - 4 \frac{4}{15} )$

1)

$- 7.2 \times 2 \frac{2}{15} = - 7.2 \times \frac{32}{15} = - 7.2 \times 2.1 = - 15.12$

2)

$- 7.2 \times 3 \frac{7}{15} = - 7.2 \times \frac{52}{15} = - 7.2 \times 3.5 = - 25.2$

3)

$- 7.2 \times ( - 4 \frac{4}{15} ) = - 7.2 \times ( - \frac{64}{15} ) = - 7.2 \times ( - 4.3) = 30.96$

4) -15,12-25,2+30,96= -40,32+30,96= -9.36
