  1. Estimate and calculate.
    1. 45\frac{4}{5}- 56\frac{5}{6}
    2. -23\frac{2}{3}- (56)\left( { - \frac{5}{6}} \right)
    3. -38\frac{3}{8} + (14)\left( { - \frac{1}{4}} \right)
    4. - 25\frac{2}{5} + (37)\left( { - \frac{3}{7}} \right)
    5. 149\frac{4}{9} + (123)\left( { - 1\frac{2}{3}} \right)
    6. 114\frac{1}{4} - 218\frac{1}{8}
    1. -113\frac{1}{3}÷ (213)\left( { - 2\frac{1}{3}} \right)
    2. -314\frac{1}{4} ÷ 112\frac{1}{2}
    3. -59\frac{5}{9} ÷ 712\frac{7}{{12}}
    4. -16\frac{1}{6}× (37)\left( { - \frac{3}{7}} \right)
    5. 115\frac{1}{5} ÷ 116\frac{1}{6}
    6. 58\frac{5}{8}(49)\left( { - \frac{4}{9}} \right)
