Answer 1

$(3- \frac{25}{12} - \frac{1}{3} + \frac{5}{3} )+ \frac{-5}{6}= \\ \\ (3- \frac{25}{12} + \frac{4}{3} ) -\frac{5}{6} = \\ \\ (3- \frac{25+16}{12} )- \frac{5}{6} = \\ \\ (3- \frac{41}{12}) - \frac{5}{6} = \\ \\ ( \frac{36-41}{12} )- \frac{5}{6} = \\ \\ - \frac{5}{12} -\frac{5}{6}= \\ \\ \frac{-5-10}{12} = \\ \\ \frac{-15}{12} = \\ \\ \frac{-5}{4}$
