Answer 1

$(5 - \frac{2}{3} ) \div (8 \frac{11}{12} - \frac{1}{4} ) \times ( \frac{2}{3} + 2 \frac{1}{6} + \frac{1}{2} ) = \frac{13}{3} \div ( \frac{107}{12} - \frac{1}{4} ) \times ( \frac{2}{3} + \frac{13}{6} + \frac{1}{2} ) = \frac{13}{3} \div \frac{26}{3} \times \frac{10}{3} = \frac{13}{3} \times \frac{3}{26} \times \frac{10}{3} = \frac{1}{2} \times \frac{10}{3} = \frac{5}{3}$
