Patrz rozwiązanie poniżej.
Szczegółowe wyjaśnienie:
[tex]\frac{1,2*\frac{3}{4} }{1,2-\frac{3}{4} } = \frac{\frac{12}{10} *\frac{3}{4} }{\frac{12}{10}-{\frac{3}{4}} } = \frac{\frac{3*4}{10}*\frac{3}{4}}{\frac{2*12}{2*10}- \frac{5*3}{5*4} } = \frac{\frac{3*3}{10} }{\frac{24}{20}- \frac{15}{20} } = \frac{\frac{9}{10} }{\frac{24-15}{20} } = \frac{\frac{9}{10} }{\frac{9}{20} } = \frac{9}{10} * \frac{20}{9} = \frac{9}{9} *\frac{20}{10} = 1 * 2 = 2[/tex]
