Question

\(\dfrac{7,5+1,5+\dfrac{5}{4}+\dfrac{5}{11}}{10,5+2,1+\dfrac{7}{4}+\dfrac{7}{11}}\)+ x = \(\dfrac{6}{7}\)

Answer 1

\(\dfrac{7,5+1,5+\dfrac{5}{4}+\dfrac{5}{11}}{10,5+2,1+\dfrac{7}{4}+\dfrac{7}{11}}+x=\dfrac{6}{7}\)

=>\(\dfrac{5\left(1,5+0,3+\dfrac{1}{4}+\dfrac{1}{11}\right)}{7\left(1,5+0,3+\dfrac{1}{4}+\dfrac{1}{11}\right)}+x=\dfrac{6}{7}\)

=>\(x+\dfrac{5}{7}=\dfrac{6}{7}\)

=>\(x=\dfrac{6}{7}-\dfrac{5}{7}=\dfrac{1}{7}\)
