Answer 1

$13 frac{7}{12} + 42 frac{1}{6} {}^{(2} = (13 + 42) + ( frac{7}{12} + frac{2}{12} ) = 55 + frac{9}{12} = 55 + frac{3}{4} = 55 frac{3}{4}$

$872 frac{5}{8} {}^{(9} + 15 frac{25}{36} {}^{(2} = (872 + 15) + ( frac{45}{72} + frac{50}{72} ) = 887 + frac{95}{72} = 887 + 1 frac{23}{72} = 888 frac{23}{72}$

$473 frac{5}{12} {}^{(7} - 362 frac{4}{21} {}^{(4} = (473 - 362) + ( frac{35}{84} - frac{16}{84} ) = 111 + frac{19}{84} = 111 frac{19}{84}$

$55 - 23 frac{51}{64} = (55 - 23) + ( frac{51}{64} ) = 32 + frac{51}{64} = 32 frac{51}{64}$

$11 times 4 frac{17}{31} = 10 frac{31}{31} times 4 frac{17}{31} = frac{341}{31} times frac{141}{31} = frac{141}{341}$

$52 frac{2}{3} div 13 = frac{158}{3} div 12 frac{3}{3} = frac{158}{3} div frac{39}{3} = frac{158}{3} times frac{3}{39} = frac{158}{39} = 4 frac{2}{39}$
