109/6

Lời giải:

\(\left[ {\frac{{109}}{6} - \left( {0,06:\frac{{15}}{2} + \frac{{17}}{5}.0,38} \right)} \right]:\left( {19 - \frac{8}{3}.\frac{{19}}{4}} \right)\)\( = \frac{{109}}{6} - \left( {\frac{1}{{125}} + \frac{{323}}{{250}}} \right):\left( {19 - \frac{{38}}{3}} \right)\)

\( = \left( {\frac{{19}}{6} - \frac{{13}}{{10}}} \right):\frac{{19}}{3} = \frac{{28}}{{15}}.\frac{3}{{19}} = \frac{{28}}{{95}}\)
