3/5×7/11+6/11×3/5-3/5×2/11
3/5×(7/11+6/11-2/11)
3/5×1
3/5
\(\frac{3}{5}\times\frac{7}{11}+\frac{6}{11}\times\frac{3}{5}-0,6\times\frac{2}{11}\)
= \(\frac{3}{5}\times\frac{7}{11}+\frac{6}{11}\times\frac{3}{5}-\frac{3}{5}\times\frac{2}{11}\)
= \(\frac{3}{5}\times\left(\frac{7}{11}+\frac{6}{11}-\frac{2}{11}\right)\)
= \(\frac{3}{5}\times\) \(\frac{11}{11}\)
= \(\frac{3}{5}\times\)\(1\)
= \(\frac{3}{5}=0,6\)
