Question

Решите 2,4:(1,5*3 1/3 - 1 4/5)​

Answer 1

Объяснение:

$2.4(1.5 \times 3 \frac{1}{3} - 1 \frac{4}{5} ) = \frac{12}{5} \times ( \frac{3}{2} \times 3 \times \frac{1}{3} - \frac{9}{5} ) = \frac{12}{5} \times ( \frac{1}{2} \times 3 - \frac{9}{5} ) = \frac{12}{5} \times ( \frac{3}{2} - \frac{9}{5} ) = \frac{12}{5} \times ( - \frac{3}{10} ) = - \frac{6}{5} \times \frac{3}{5} = - \frac{18}{25} = - 0.72$
