Вычислите: 6/7 × 14/15; 10/21 × 7/20; 17/18 × 1; 8/11 × 0; 7/15 : 14/25; 13/16 : 1/32; 11/12 × 6; 0 : 2 1/7; 3 5/16 × 1.

1. \(\frac{6}{7}\times\frac{14}{15}=\frac{6\times14}{7\times15}=\frac{4}{5}\).
2. \(\frac{10}{21}\times\frac{7}{20}=\frac{1}{6}\).
3. \(\frac{17}{18}\times1=\frac{17}{18}\).
4. \(\frac{8}{11}\times0=0\).
5. \(\frac{7}{15}:\frac{14}{25}=\frac{7}{15}\times\frac{25}{14}=\frac{5}{6}\).
6. \(\frac{13}{16}:\frac{1}{32}=\frac{13}{16}\times32=26\).
7. \(\frac{11}{12}\times6=\frac{11}{2}=5\frac{1}{2}\).
8. \(0:2\frac{1}{7}=0\).
9. \(3\frac{5}{16}\times1=3\frac{5}{16}\).

Ответ: \(\frac{4}{5};\ \frac{1}{6};\ \frac{17}{18};\ 0;\ \frac{5}{6};\ 26;\ 5\frac{1}{2};\ 0;\ 3\frac{5}{16}\).
