[tex]3,6:\frac{3}{5}-1\frac{1}{5}=\frac{36}{10}*\frac{5}{3}=1\frac{1}{5}=[/tex]
[tex]\frac{12}{2}-1\frac{1}{5}=6-1\frac{1}{5}=5\frac{5}{5}-1\frac{1}{5}=4\frac{4}{5}[/tex]

[tex]3,6:0,6-\frac{6}{5}=6-\frac{6}{5}=\frac{24}{5}=4\frac{4}{5}=4,8[/tex]
e)
[tex]23,5+7,65:3^{2}=23,5+7,65:9=23,5+0,85=24,35[/tex]
