Question

(-1 3/7 ×4 2/3+1 7/9) × (-3/4)

Answer 1

Пошаговое объяснение:

$( - 1 \frac{3}{7} \times 4 \frac{2}{3} + 1 \frac{7}{9} ) \times ( - \frac{3}{4}) \\ ( - \frac{10}{7} \times 4 \times \frac{2}{3} + \frac{16}{9} ) \times ( - \frac{3}{4} ) \\ ( - \frac{80}{21} + \frac{16}{9} ) \times ( - \frac{3}{4} )$

$- \frac{128}{63} \times ( - \frac{3}{4} ) = \frac{32}{21} = 1 \frac{11}{21}$
