Question

8)7,5*(-0,01)*1/10*(-1 1/3)*1/40

Answer 1

Ответ:

$7.5 \times ( - 0.01) \times \frac{1}{10} \times ( - 1 \frac{1}{3} ) \times \frac{1}{40} = \\ 7.5 \times ( - 0.01) = - 0.075 \\ - 0.075 \times \frac{1}{10} = - 0.075 \times 0.1 = - 0.0075 \\ - 0.0075 \times ( - 1 \frac{1}{3} ) = - \frac{3}{400} \times ( - \frac{4}{3} ) = \frac{1}{100} \\ \frac{1}{100} \times \frac{1}{40} = \frac{1}{4000}$
