Answer 1

$(2 \frac{13}{48} - ( - 2 \frac{5}{12} )) \div ( - 3 \frac{3}{4} )+ 9 \frac{3}{4} \div ( - 13) = ( \frac{109}{48} + \frac{29}{12} ) \div ( - \frac{15}{4}) + \frac{39}{4} \div ( - \frac{13}{1} ) = ( \frac{109}{48} + \frac{116}{48} ) \times ( - \frac{4}{15} ) + \frac{39}{4} \times ( - \frac{1}{13} )= \frac{225}{48} \times ( - \frac{4}{15} ) - \frac{39}{52} = - \frac{15 \times 1}{12 \times 1} - \frac{3}{4} = - \frac{15}{12} - \frac{9}{12} = - \frac{24}{12} = - \frac{1}{2}$
