Odpowiedź:
[tex]1\frac{3}{5}-\frac{3}{5}:(\frac{1}{2}+\frac{3}{5})=1\frac{3}{5}-\frac{3}{5}:(\frac{5}{10}+\frac{6}{10})=1\frac{3}{5}-\frac{3}{5}:\frac{11}{10}=1\frac{3}{5}-\frac{3}{5}*\frac{10}{11}=1\frac{3}{5}-\frac{6}{11}=1\frac{33}{55}-\frac{30}{55}=1\frac{3}{55}[/tex]
Szczegółowe wyjaśnienie:
1 3/5-3/5:(1/2+3/5)=1 3/5-3/5:(5/10+6/10)=1 3/5-3/5:1 1/10=1 3/5-3/5:11/10=
=1 3/5-3/5·10/11=1 3/5-6/11=1 33/55-30/55=1 3/55
