\(B=\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{1}{34}+\frac{3}{20}-\frac{3}{26}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Tính :
\(\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{1}{34}+\frac{3}{20}-\frac{3}{26}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
\(A=\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{1}{34}+\frac{3}{20}-\frac{3}{26}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Tính \(A=\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{3}{26}-\frac{3}{20}-\frac{1}{34}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Tính A = \(\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{3}{26}-\frac{3}{20}-\frac{1}{34}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Tính A theo cách hợp lý: \(A=\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{3}{26}-\frac{3}{20}-\frac{1}{34}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)

tính bằng cách hợp lí:
\(B=\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{1}{34}+\frac{3}{20}-\frac{3}{26}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Cho \(A=\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{3}{26}-\frac{3}{20}-\frac{1}{34}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
Tính A theo cách hợp lý.
tính A=\(\frac{\frac{2}{39}-\frac{1}{15}-\frac{2}{153}}{\frac{1}{85}+\frac{3}{50}+\frac{3}{65}}:\frac{1+\frac{2}{71}-\frac{5}{121}}{\frac{65}{121}-\frac{26}{71}-13}\)
