\(=\frac{5.11.3.7.11.13-3.7.11.13}{120.10101+4.10101}=\frac{3.7.11.13\left(5.11-1\right)}{10101\left(120+4\right)}=\frac{10101.54}{10101.124}=\frac{54}{124}=\frac{27}{62}\)
\(A=\frac{3.5.7.11.13.37-10101}{1212120+40404}\)
\(A=\frac{\left(3.7.13.17\right).\left(5.11\right)-10101}{120.10101+4.10101}\)
\(A=\frac{10101.55-10101.1}{120.10101+4.10101}\)
\(A=\frac{10101.\left(55-1\right)}{10101.\left(120+4\right)}\)
\(A=\frac{10101.54}{10101.124}\)
\(A=\frac{54}{124}\)
\(A=\frac{27}{62}\)

\(A=\frac{3x5x7x11x13x37-10101}{1212120+40404}=\frac{545454}{1252524}=\frac{27}{62}\)

A=3*5*7*11*13*37-10101/1212120+40404
A=10101*(55-1)/10101*(120+4)
A=55-1/120+4
A=54/124=27/62
A=\(\frac{\left(5.11\right)\left(3.7.13.37\right)-10101}{12.10101+4.10101}\)
A=\(\frac{55.10101-10101}{12.10101+4.10101}\)
A=\(\frac{54.10101}{16.10101}\)
A=\(\frac{54}{16}=3,375\)
\(\frac{3.5.7.11.13.37+10101}{1212120+40404}=\frac{555555+10101}{1212120+40404}\)
\(=\frac{55.10101+10101}{120.10101+4.10101}\)
\(=\frac{\left(55+1\right).10101}{\left(120+4\right).10101}\)
\(=\frac{56}{124}=\frac{14}{31}\)
