Question 2

1)
$( { (\frac{18}{10})}^{2} - \frac{23}{10} \times \frac{9}{5} ) \div \frac{18}{7} = ( \frac{324}{100} - \frac{207}{50} ) \times \frac{7}{18} = \frac{324 - 414}{50} \times \frac{7}{18} = \frac{ - 90}{50} \times \frac{7}{18} = - \frac{7}{10}$
2)
$= ( \frac{9}{5} \times \frac{11}{10} - ( \frac{16}{10} )^{2} ) \div \frac{8}{3} = ( \frac{88}{50} - \frac{256}{100} ) \times \frac{3}{8} = \frac{176 - 256}{100} \times \frac{3}{8} = \frac{ - 80}{100} \times \frac{3}{8} = - \frac{3}{10}$
3)
$= ( {( \frac{15}{10}) }^{2} - \frac{11}{5} \times \frac{3}{2}) \div \frac{7}{4} = ( \frac{225}{100} - \frac{33}{10} ) \times \frac{4}{7} = \frac{225 - 330}{100} \times \frac{4}{7} = \frac{ - 105}{100} \times \frac{4}{7} = \frac{ - 6}{10}$
4)
$= ( \frac{9}{10} \times \frac{7}{5} - { (\frac{14}{10} )}^{2} ) \div \frac{7}{3} = ( \frac{63}{50} - \frac{196}{100} ) \times \frac{3}{7} = \frac{ 126 - 196}{100} \times \frac{3}{7} = \frac{ - 70}{100} \times \frac{3}{7} = - \frac{3}{10}$

5)
$\frac{33}{8} - \frac{9}{4} \times ( \frac{4}{3} \div \frac{9}{4} + 2) = \frac{33}{8} - \frac{9}{4} \times ( \frac{4}{3} \times \frac{4}{9} + 2) = \frac{33}{8} - \frac{9}{4} ( \frac{16}{27} + \frac{54}{27} ) = \frac{33}{8} - \frac{9}{4} \times \frac{70}{27} = \frac{33}{8} - \frac{630}{108} = \frac{891 - 1260}{216} = - \frac{369}{216} = - \frac{41}{24}$
