Question

Rút gọn biểu thức: 

A=\(\frac{3.5.7.11.13.37-10101}{1212120+40404}\)

Answer 1

\(A=\frac{3.5.7.11.13.37-10101}{1212120+40404}\)

\(A=\frac{\left(3.7.13.17\right).\left(5.11\right)-10101}{120.10101+4.10101}\)

\(A=\frac{10101.55-10101.1}{120.10101+4.10101}\)

\(A=\frac{10101.\left(55-1\right)}{10101.\left(120+4\right)}\)

\(A=\frac{10101.54}{10101.124}\)

\(A=\frac{54}{124}\)

\(A=\frac{27}{62}\)
