What approximate value should come in place of the question mark (?) in the following question?
\(14\frac{6}{7}+15\frac{2}{7} - 5\frac{2}{3}\times3\frac{1}{2}=?\)
Now, $(14\frac{6}{7}+15\frac{2}{7} - 5\frac{2}{3}\times3\frac{1}{2}=?)$
$(\begin{array}{l} = \frac{{104}}{7} + \frac{{107}}{7} - \frac{{17}}{3} \times \frac{7}{2}\\ = \frac{{211}}{7} - \frac{{119}}{6} \end{array})$
$(\begin{array}{l} = \frac{{1266\;-\;833}}{{42}}\\ = \frac{{433}}{{42}}\\ =\;?=10\frac{{13}}{{42}} \end{array})$
