\( \large \Large \frac{{{5^{ - 5}} \cdot {{0,1}^{ - 4}} + {{\left( {\frac{1}{7}} \right) }^{0}} - {5^{ - 1}}}}{{{{\left( { - 2} \right) }^{ - 2}} \cdot {{\left( { - \frac{1}{2}} \right) }^{ - 4}} + {{\left( { - \frac{1}{2}} \right) }^{ - 1}}}}\large \)
\( \large = \Large \frac{{\frac{{20}}{5}}}{2}\large = \Large \frac{4}{2}\large = 4 : 2 = 2 \)
\( \large = \Large \frac{{\frac{{15}}{5}}}{2}\large = \Large \frac{3}{2}\large = 3 : 2 = 1.5 \)
\( \large = \Large \frac{{\frac{{10}}{5}}}{2}\large = \Large \frac{2}{2}\large = 2 : 2 = 1 \)
\( \large = \Large \frac{{\frac{{25}}{5}}}{2}\large = \Large \frac{5}{2}\large = 5 : 2 = 2.5 \)
