Szczegółowe wyjaśnienie:
[tex]( \frac{7}{3} - \frac{5}{12} + \frac{11}{2} ) \div (2 \frac{3}{4} ) =( \frac{28}{12} - \frac{5}{12} + \frac{11}{2} ) \div (\frac{11}{4} - \frac{5}{6} ) = (\frac{23}{12 } + \frac{11}{2}) \div (\frac{66}{24} - \frac{20}{24} ) =( \frac{23}{12} + \frac{66}{12} ) \div \frac{46}{24} = \frac{89}{12} \div \frac{46}{24} = \frac{89}{1} \times \frac{2}{46} = \frac{178}{46} = 3 \frac{40}{46} = 3 \frac{20}{23} [/tex]
