ПРОШУ! У МЕНЯ МАЛО ВРЕМЕНИ!!!!
ПОЖАЛУЙСТА!!

Answer 1

$1) frac{3}{7} + frac{5}{6} = frac{18}{42} + frac{35}{42} = frac{53}{45} = 1 frac{8}{45}$

$2) frac{5}{14} times frac{7}{30} = frac{1}{12}$

$frac{11}{12} - frac{7}{8} = frac{22}{24} - frac{21}{24} = frac{1}{24}$

$1 frac{8}{25} times 1 frac{4}{11} = frac{33}{25} times frac{15}{11} = frac{9}{5} = 1 frac{4}{5} = \ = 1.8$

$frac{5}{9} div frac{10}{27} = frac{5}{9} times frac{27}{10} = frac{3}{2} = 1 frac{1}{2} = 1.5$

$4 frac{4}{9} div 1 frac{2}{3} = frac{40}{9} times frac{3}{5} = frac{8}{3} = 2 frac{2}{3}$

$14 - (6 frac{8}{16} + 3 frac{4}{16} ) = 14 - 9 frac{12}{16} = \ = 13 frac{16}{16} - 9 frac{12}{16} = 4 frac{4}{16} = 4 frac{1}{4}$

$7 frac{1}{3} times ( frac{9}{20} div frac{1}{30} ) = 7 frac{1}{3} times \ ( frac{9}{20} times frac{30}{1} ) = 7 frac{1}{3} times frac{27}{2} =$

$frac{22}{3} times frac{27}{2} = 99$
