Odpowiedź :

[tex]\dfrac{1\frac79-\frac13}{\frac59-0,6:1\frac45}=\dfrac{1\frac79-\frac39}{\frac59-\frac6{10}:\frac95}=\dfrac{1\frac49}{\frac59-\frac6{10}\cdot\frac59}=\dfrac{1\frac49}{\frac59-\frac26}=\\=\dfrac{1\frac49}{\frac{10}{18}-\frac6{18}}=\dfrac{1\frac49}{\frac4{18}}=1\dfrac49:\dfrac4{18}=\dfrac{13}9\cdot\dfrac{18}{4}=\dfrac{26}{4}=6\dfrac24=6\dfrac12[/tex]

Odpowiedź:

[tex]\frac{1\frac{7}{9}-1\frac{1}{3} }{\frac{5}{9}-0,6:1\frac{4}5} =\frac{1\frac{21}{27}-1\frac{9}{27} }{\frac{5}{9}-\frac{3}{5} *\frac{5}{9} }= \frac{\frac{12}{27} }{\frac{5}{9}-\frac{1}{3} }=\frac{\frac{12}{27} }{\frac{5}{9}- \frac{3}{9} }=\frac{\frac{12}{27} }{\frac{2}{9} }=\frac{12}{27}*\frac{9}{2}=\frac{6}{3}=2[/tex]
