Пошаговое объяснение:
[tex]1 \frac{3}{7} \times 2 \frac{1}{3} = \frac{1 \times 7 + 3}{7} \times \frac{2 \times 3 + 1}{3} = \frac{7 + 3}{7} [/tex]
[tex] \times \frac{6 + 1}{3} = \frac{10}{7} \times \frac{7}{3} = \frac{10 \times 7}{7 \times 3} = \frac{70}{21} [/tex]
[tex] = \frac{10 \times 7}{3 \times 7} = \frac{10}{3} = 3 \frac{1}{3} [/tex]
