Question

(3 5/6-2 3/4):7/12+8 1/2=

Answer 1

вроде бы так
$(3 \frac{5}{3 } - 2 \frac{3}{4} ) \div \frac{7}{12} + 8 \frac{1}{2} = ( \frac{56}{12} - \ \\ \frac{33}{12} ) \div \frac{7}{12} + \frac{17}{2} = \frac{23}{12} \div \frac{7}{12} + \frac{17}{2} = ( \frac{23}{12} \times \frac{12}{7} ) + \frac{17}{2} = \frac{23}{7} + \frac{17}{2} = \frac{119 + 46}{14} = \frac{165}{14} = 11 \frac{11}{14}$
