\(C=10101.\left(\frac{5}{111111}+\frac{5}{222222}+\frac{4}{3.7.11.13.37}\right)\)
\(C=10101.\frac{23}{222222}\)
\(C=\frac{23}{22}.\)
\(10101\cdot\left(\dfrac{5}{111111}+\dfrac{5}{222222}-\dfrac{4}{3\cdot7\cdot11\cdot13\cdot37}\right)\)=\(10101\cdot\left(\dfrac{5}{111111}+\dfrac{5}{222222}-\dfrac{4}{111111}\right)\)
= \(10101\cdot\left(\dfrac{5}{111111}-\dfrac{4}{111111}+\dfrac{5}{222222}\right)\)
= \(10101\cdot\left(\dfrac{1}{111111}+\dfrac{5}{222222}\right)\)
= \(10101\cdot\left(\dfrac{2}{222222}+\dfrac{5}{222222}\right)\)
= \(10101\cdot\dfrac{7}{222222}\)
= \(\dfrac{10101\cdot7}{222222}=\dfrac{10101\cdot7}{10101\cdot22}=\dfrac{7}{22}\)
10101.(\(\dfrac{5}{111111}+\dfrac{5}{222222}-\dfrac{4}{3.7.11.13.37}\))
= 10101.(\(\dfrac{5}{111111}+\dfrac{5}{222222}-\dfrac{4}{111111}\))
= 10101.(\(\dfrac{1}{111111}+\dfrac{5}{222222}\))
= 10101. \(\dfrac{7}{222222}\)
= \(\dfrac{10101.7}{222222}\)= \(\dfrac{70707}{22222}\)=\(\dfrac{7}{22}\)
Chúc pạn hok tốt!!!!!!!
=\(10101.\left(\frac{5}{111111}+\frac{5}{222222}.\frac{4}{111111}\right)\)
=\(10101.\left(\frac{5}{111111}+\frac{20}{24691308642}\right)\)
=\(10101.\frac{1111130}{24691308642}\)
=0,4545........
