Question

Решите пожалуйста 3) пункт

Answer 1

<u />$1) 2\frac{3}{8} : \frac{3}{4}= \frac{19*4}{8*3}= \frac{19}{2*3} = \frac{19}{6}=3 \frac{1}{6}$

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

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

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

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