Answer 1

7)
$\frac{5 \frac{2}{3}+1\frac{1}{3} +4 \frac{1}{3} }{1+ \frac{1}{3+ \frac{1}{2} } } = \frac{ \frac{17}{3}+ \frac{4}{3}+ \frac{13}{3} }{1+ \frac{2}{7} } = \frac{ \frac{34}{3} }{ \frac{9}{7} } = \frac{238}{27} = 8\frac{22}{27}$


9)
$[ (\frac{36}{15} )( \frac{-12}{8} )( \frac{-3}{12} )][( \frac{24}{13} )( \frac{-87}{58} )( \frac{169}{36} )]=[ \frac{1296}{1440} ][ \frac{-352872}{27144} ]=[ \frac{9}{10} ][ -13 ]= \frac{-117}{10}$
