\(\left(\frac{1}{5}+\frac{1}{35}+\frac{1}{62}\right)\times x=1\)
\(\frac{531}{2170}\times x=1\)
\(x=1\div\frac{531}{2170}\)
\(x=\frac{748}{217}\)
=))
\(\left(\frac{1}{5}+\frac{1}{35}+\frac{1}{62}\right)\cdot x=1\)
\(x=1:\left(\frac{1}{5}+\frac{1}{35}+\frac{1}{62}\right)\)
\(x=1:\frac{1}{5}+1:\frac{1}{35}+1:\frac{1}{62}\)
\(x=5+35+62\)
\(x=102\)

Sửa đề :)
\(\left(\frac{1}{5}+\frac{1}{35}+\frac{1}{63}\right)x=1\)
\(\left(\frac{1}{1.5}+\frac{1}{5.7}+\frac{1}{7.9}\right)=\frac{1}{x}\)
\(\left(1-\frac{1}{5}+\frac{1}{5}-\frac{1}{7}+\frac{1}{7}-\frac{1}{9}\right)=\frac{1}{x}\)
\(\left(1-\frac{1}{9}\right)=\frac{1}{x}\)
\(\frac{8}{9}=\frac{1}{x}\)
\(\Rightarrow x=\frac{9}{8}\)
\(\left(\frac{1}{5}+\frac{1}{35}+\frac{1}{62}\right)\times X=1\)
\(\Rightarrow\frac{531}{2170}\times X=1\)
\(\Rightarrow X=1:\frac{531}{2170}\)
\(\Rightarrow X=\frac{2170}{531}\)
Vậy:....................
Trả lời:
x = 748/217
