[tex] \frac{5}{6} [/tex]

Пошаговое объяснение:

[tex](2 \frac{1}{4} + 4 \frac{5}{6} ) \div 3 \frac{2}{5} - \frac{3}{4} \div \frac{3}{5} = \\ = ( \frac{9}{4} + \frac{29}{6} ) \div \frac{17}{5} - \\ - \frac{3}{4} \div \frac{3}{5} = \\ = ( \frac{9 \times 6 + 29 \times 4}{4 \times 6} ) \times \frac{5}{17 } - \\ - \frac{3}{4} \times \frac{5}{3} = \\ = ( \frac{54 + 116}{24}) \times \frac{5}{17} - \frac{5}{4} = \\ = \frac{170}{24} \times \frac{5}{17} - \frac{5}{4} = \\ = \frac{50}{24} - \frac{5}{4} = \\ = \frac{50}{24} - \frac{30}{24} = \\ = \frac{20}{24} = \frac{5}{6} [/tex]
