\(C=10101.\left(\frac{5}{111111}+\frac{5}{222222}+\frac{4}{3.7.11.13.37}\right)\)

\(C=10101.\frac{23}{222222}\)

\(C=\frac{23}{22}.\)

111111=3.7.11.13.37

222222=2.3.7.11.13.37

THẾ ZÔ LM TIẾP

Làm rõ hơn đi bạn 

\(B=10101\cdot\left(\dfrac{5}{111111}+\dfrac{5}{222222}-\dfrac{4}{111111}\right)\)

\(=10101\cdot\left(\dfrac{2}{222222}+\dfrac{5}{222222}\right)\)

\(=10101\cdot\dfrac{1}{31746}=\dfrac{7}{22}\)

A=7/22

Ai thấy đúng thì k cho mik nha

A=6/11 bạn ơi

\(A=10101.\left(\frac{5}{111111}+\frac{5}{222222}-\frac{4}{3.7.11.13.37}\right)\)

\(A=10101.\left(\frac{5}{111111}+\frac{5}{222222}-\frac{4}{111111}\right)\)

\(A=10101.\left(\frac{10}{222222}+\frac{5}{222222}-\frac{8}{222222}\right)\)

\(A=10101.\left(\frac{7}{222222}\right)\)

\(A=\frac{70707}{222222}\)

\(A=\frac{7}{22}\)

Vậy A = \(\frac{7}{22}\)

Chúc bạn học tốt!

\(10101\cdot\left(\dfrac{5}{111111}+\dfrac{5}{222222}-\dfrac{4}{3\cdot7\cdot11\cdot13\cdot37}\right)\)=\(10101\cdot\left(\dfrac{5}{111111}+\dfrac{5}{222222}-\dfrac{4}{111111}\right)\)

= \(10101\cdot\left(\dfrac{5}{111111}-\dfrac{4}{111111}+\dfrac{5}{222222}\right)\)

= \(10101\cdot\left(\dfrac{1}{111111}+\dfrac{5}{222222}\right)\)

= \(10101\cdot\left(\dfrac{2}{222222}+\dfrac{5}{222222}\right)\)

= \(10101\cdot\dfrac{7}{222222}\)

= \(\dfrac{10101\cdot7}{222222}=\dfrac{10101\cdot7}{10101\cdot22}=\dfrac{7}{22}\)

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!!!!!!!
