Tìm x nha mn

Answer 1

\(\left(1-\frac{1}{2}-\frac{1}{6}-\frac{1}{12}-\frac{1}{20}-\frac{1}{30}\right)\cdot X=\frac{11}{6}\)

\(< =>\left(\frac{1}{2}-\frac{1}{12}-\frac{1}{60}\right)\cdot X=\frac{11}{6}\)

\(< =>\left(\frac{30}{60}-\frac{5}{60}-\frac{1}{60}\right)\cdot X=\frac{11}{6}\)

\(< =>\left(\frac{30-5-1}{60}\right)\cdot X=\frac{11}{6}\)

\(< =>\frac{2}{5}\cdot X=\frac{11}{6}\)

\(< =>X=\frac{11}{6}:\frac{2}{5}\)

\(< =>X=\frac{55}{12}\)
