1 2/3(0,75 * 6) - 5/9(0,6 * 0,75 - 2,7)

Answer 1

Ответ:

$1 \frac{2}{3} (0.75 \times 6) - \frac{5}{9}(0.6 \times 0.75 - 2.7) = 1 \frac{2}{3} \times 4.5 - \frac{5}{9} (0.45 - 2.7) = \frac{5}{3} \times \frac{45}{10} - \frac{5}{9} \times ( - 2.25) = \frac{5 \times 45}{3 \times 10} + \frac{5}{9} \times \frac{9}{4} = \frac{15}{2} + \frac{5}{4} = 7.5 + 1.25 = 8.75$
