$75.84 \div 8 = \frac{7584}{100} \div 8 = \frac{948}{100} = 9.48$

$3.8 \div 0.1 = \frac{38}{10} \div \frac{1}{10} = \frac{38}{10} \times 10 = 38$

$0.102 \div 0.001 = \frac{102}{1000} \div \frac{1}{1000} = \frac{102}{1000} \times 1000 = 102$

$12.1\div 1.1=\frac{121}{10}\div \frac{11}{10}=\frac{121}{10} \times \frac{10}{11}=11$

$121\div 1.1=121\div \frac{11}{10}=121\times \frac{10}{11}=110$

нет

$54.1\div 1.21=\frac{541}{10}\div \frac{121}{100}=\frac{541}{10} \times \frac{100}{121}=\frac{5410}{121}$

$541\div 121=\frac{541}{121}$

нет

$732.589\div 0.27=\frac{732589}{1000}\div \frac{27}{100}=\frac{732589}{1000} \times \frac{100}{27}=\frac{732589}{270}$

$73258.9 \div 27 = \frac{732589}{10}\div 27=\frac{732589}{270}$

да

$10.048 \div 3.2= \frac{10048}{1000}\div \frac{32}{10}=\frac{10048}{1000}\times \frac{10}{32}=\frac{314}{100}=3.14$

$100.48 \div 3.2=\frac{10048}{100}\div \frac{32}{10}=\frac{10048}{100}\times \frac{10}{32}=\frac{314}{10}=31.4$

$1.0048 \div 3.2=\frac{10048}{10000}\div \frac{32}{10}=\frac{10048}{10000}\times \frac{10}{32}=\frac{314}{1000}=0.314$

$93.1 \times 0.23=21.413$

$8.8 \times 1.7= 14.96$

$2.2 \times 1.8=3.96$

$0.7 \times 1.2=0.84$

$0.6 \times 0.92=0.552$

$1.02 \times 0.8=0.816$

$20.7 \times 0.9=18.63$
