\( \frac{5}{6} x \frac{3}{11} = \frac{5 x 3}{6 x 11} = \frac{15}{66} \)
\( \frac{15}{66} = \frac{5}{22} \)
\( \frac{5}{22} + \frac{8}{25} = \frac{5 x 25}{22 x 25} + \frac{8 x 22}{25 x 22} = \frac{125}{550} + \frac{176}{550} = \frac{125 + 176}{550} = \frac{301}{550} \)
\( \frac{301}{550} : \frac{2}{5} = \frac{301}{550} x \frac{5}{2} \)
\( \frac{301}{550} x \frac{5}{2} = \frac{301}{110 x 5} x \frac{5}{2} = \frac{301}{110 x 2} = \frac{301}{220} \)
\( -4,1 - \frac{301}{220} \)
\( -\frac{41}{10} = -\frac{41 x 22}{10 x 22} = -\frac{902}{220} \)
\( -\frac{902}{220} - \frac{301}{220} = \frac{-902 - 301}{220} = \frac{-1203}{220} \)
\( -1203 \div 220 \)
\( 1203 = 5 x 220 + 103 \)
\( -\frac{1203}{220} = -5 \frac{103}{220} \)
Ответ: -5 \(\frac{103}{220}\).
