Răspuns:

$( \frac{5}{6} + 1 \frac{5}{8} ) \div ( \frac{1}{2} )^{2} - 9 \frac{1}{3} =$

$= ( \frac{5}{6} + \frac{1 \times 8 + 5}{8} ) \div \frac{1}{4} - \frac{9 \times 3 + 1}{3} =$

$= ( \frac{5}{6} + \frac{13}{8} ) \div \frac{1}{4} - \frac{28}{3} =$

$= ( \frac{5 \times 4 }{24} + \frac{13 \times 3 }{24} ) \div \frac{1}{4} - \frac{28}{3} =$

$= \frac{20 + 39}{24} \div \frac{1}{4} - \frac{28}{3} =$

$= \frac{59}{24} \times 4 - \frac{28}{3} =$

$= \frac{59}{6} - \frac{28}{3} =$

$= \frac{59}{6} - \frac{28 \times 2}{6} = \frac{59 + 56}{6} = \frac{115}{6}$
