Question

(4 5/12 - 3 13/24) : 1 3/4 + 5/6 × 3/5​

Answer 1

Ответ:

$(4 \frac{5}{12} - 3 \frac{13}{24} ) \div 1 \frac{3}{4} + \frac{5}{6} \times \frac{3}{5} = ( \frac{53}{12} - \frac{85}{24} ) \div \frac{7}{4} + \frac{5}{6} \times \frac{3}{5} = \frac{106 - 85}{24} \div \frac{7}{4} + \frac{1}{2} = \frac{21}{24} \times \frac{4}{7} + \frac{1}{2} = \frac{3}{6} \times \frac{4}{7} + \frac{1}{2} = \frac{12}{42} + \frac{1}{2} = \frac{12 + 21}{42} = \frac{33}{42} = \frac{11}{14}$
