Найдите чему равны следующие произведения 3/4*1 1/3 2/11*1 5/6 3 5/9*4 7/8

Решите задачу:

$\frac{3}{4} \times 1 \frac{1}{3} \times \frac{2}{11} \times 1 \frac{5}{6} \times 3 \frac{5}{9} \times 4 \frac{7}{8} =$

$= \frac{3}{4} \times \frac{4}{3} \times \frac{2}{11} \times \frac{11}{6} \times \frac{32}{9} \times \frac{39}{8} =$

$= \frac{3 \times 4 \times 2 \times 11 \times 32 \times 39}{4 \times 3 \times 11 \times 6 \times 9 \times 8} = \frac{2 \times 11 \times 32 \times 39}{11 \times 6 \times 9 \times 8} =$

$= \frac{2 \times 32 \times 39}{6 \times 9 \times 8} = \frac{32 \times 39}{6 \times 9 \times 4} = \frac{8 \times 39}{6 \times 9} =$

$= \frac{4 \times 39}{3 \times 9} = \frac{4 \times 13}{9} = \frac{52}{9} = 5 \frac{7}{9}$
