Szczegółowe wyjaśnienie:
a) [tex](3\frac{3}{5}+2\frac{4}{5}):\frac{6}{7}=5\frac{7}{5}*\frac{7}{6}=\frac{32}{5}*\frac{7}{6}=(skracamy)=\frac{16}{5}*\frac{7}{3}=\frac{112}{15}=7\frac{7}{15}[/tex]
b)
[tex]\frac{3}{4}:4\frac{1}{2}+7:1\frac{1}{6}=\frac{3}{4}:\frac{9}{2}+7:\frac{7}{6}=\frac{3}{4}*\frac{2}{9}+7*\frac{6}{7}=(skracamy)=\frac{1}{2}*\frac{1}{3}+1*\frac{6}{1}=\frac{1}{6}+6=6\frac{1}{6}[/tex]
c)
[tex]\frac{3}{5}:(1\frac{1}{2}-\frac{3}{4})=\frac{3}{5}:(1\frac{2}{4}-\frac{3}{4})=\frac{3}{5}:(\frac{6}{4}-\frac{3}{4})=\frac{3}{5}:\frac{3}{4}=\frac{3}{5}*\frac{4}{3}=(skracamy)=\frac{1}{5}*\frac{4}{1}=\frac{4}{5}[/tex]
