Szczegółowe wyjaśnienie:
[tex]1-(-3\frac{1}{3} *(2,24-2\frac{1}{4} ))=[/tex] [ [tex]2\frac{1}{4} =2\frac{25}{100} =2,25[/tex] ]
[tex]=1-(-3\frac{1}{3} *(2,24-2,25))=[/tex]
[tex]=1-(-3\frac{1}{3} *(-0,01))=[/tex]
[tex]=1-(-\frac{10}{3} *(-\frac{1}{100} ))=[/tex]
[tex]=1-(\frac{10}{3} *\frac{1}{100} )=[/tex] [skracamy 10 i 100 przez 10 ]
[tex]=1-(\frac{1}{3} *\frac{1}{10} )=1-\frac{1}{30} =\frac{30}{30}-\frac{1}{30}=\frac{29}{30}[/tex]
