Question

Решите пожалуйста 3) пункт

Answer 1

$1) 2frac{3}{8} : frac{3}{4}= frac{19*4}{8*3}= frac{19}{2*3} = frac{19}{6}=3 frac{1}{6}$

$2) 3frac{1}{6}+ 24frac{7}{9} = 3frac{3}{18}+ 24frac{14}{18} =27 frac{17}{18}$

$3) 157 frac{4}{5} :24= frac{789*1}{5*24} = frac{263}{5*8} = frac{263}{40} = 6frac{23}{40}$

$7frac{1}{8}- 6frac{23}{40}= 7frac{5}{40} - 6frac{23}{40}= 6frac{45}{40}- 6frac{23}{40} = frac{22}{40}= frac{11}{20}$

$27 frac{17}{18}: frac{11}{20}= frac{503*20}{18*11}= frac{503*10}{9*11} = frac{5030}{99}= 50frac{80}{99}$
