Числитель 0,51*0,36:5/6 знаменатель 3/5*1,7*(1,8+3/4) решить дробь

$\frac{0.51*0.36: \frac{5}{6} }{ \frac{3}{5}*1.7*(1.8+ \frac{3}{4})}=\frac{ \frac{51*9*3}{25*50*5} }{ \frac{3*17*51}{5*10*20} } = \frac{51*9*3}{20*50*5}: \frac{3*17*51}{5*10*20}= \frac{51*9*3}{25*50*5}* \frac{5*10*20}{3*17*51}= \frac{9*4}{25*17}= \frac{36}{425}$

$0.51*0.36: \frac{5}{6} = \frac{51}{100}* \frac{36}{100}* \frac{6}{5}= \frac{51*9*3}{25*50*5}$
1,8+3/4=1 8/10+3/4=1 4/5+3/4=1 16/20+15/20=1 31/20=2 11/20
$\frac{3}{5}*1,7*2 \frac{11}{20} = \frac{3}{5}*1 \frac{7}{10}*2 \frac{11}{20}= \frac{3}{5}* \frac{17}{10}* \frac{51}{20}$
