Answer 1

$(14 - 2 \frac{11}{12} \div \frac{7}{18} ) \div 4 \frac{7}{8} + 3 \frac{3}{4} \times \frac{7}{9} = (14 - \frac{35}{12} \times \frac{18}{7} ) \div \frac{39}{8} + \frac{15}{4} \times \frac{7}{9} = (14 - \frac{5}{2} \times 3) \times \frac{8}{39} + \frac{5}{4} \times \frac{7}{3} = (14 - \frac{15}{2} ) \times \frac{8}{39} + \frac{35}{12} = ( \frac{28 - 15}{2} ) \times \frac{8}{39} + \frac{35}{12} = \frac{13}{2} \times \frac{8}{39} + \frac{35}{12} = \frac{4}{3} + \frac{35}{12} = \frac{16 + 35}{12} = \frac{51}{12} = \frac{17}{4} = 4 \frac{1}{4} .$
