Ответ:
- \(\frac{1}{22}-\frac{1}{24}=\frac{24-22}{22\cdot24}=\frac{2}{528}=\frac{1}{264}\), поэтому \(\frac{1}{\frac{1}{22}-\frac{1}{24}}=264\).
- \(\frac{1}{56}+\frac{1}{44}=\frac{44+56}{56\cdot44}=\frac{100}{2464}=\frac{25}{616}\), поэтому \(\frac{1}{\frac{1}{56}+\frac{1}{44}}=\frac{616}{25}\).
- \(\frac{1}{35}+\frac{1}{20}=\frac{20+35}{35\cdot20}=\frac{55}{700}=\frac{11}{140}\), поэтому \(\frac{1}{\frac{1}{35}+\frac{1}{20}}=\frac{140}{11}\).
- \(\frac{1}{25}-\frac{1}{15}=\frac{15-25}{25\cdot15}=\frac{-10}{375}=-\frac{2}{75}\), поэтому \(\frac{1}{\frac{1}{25}-\frac{1}{15}}=-\frac{75}{2}\).
- \(\frac{1}{18}-\frac{1}{12}=\frac{12-18}{18\cdot12}=\frac{-6}{216}=-\frac{1}{36}\), поэтому \(\frac{1}{\frac{1}{18}-\frac{1}{12}}=-36\).
- \(\frac{1}{55}+\frac{1}{25}=\frac{25+55}{55\cdot25}=\frac{80}{1375}=\frac{16}{275}\), поэтому \(\frac{1}{\frac{1}{55}+\frac{1}{25}}=\frac{275}{16}\).
- \(\frac{1}{15}-\frac{1}{12}=\frac{12-15}{15\cdot12}=\frac{-3}{180}=-\frac{1}{60}\), поэтому \(\frac{1}{\frac{1}{15}-\frac{1}{12}}=-60\).
- \(\frac{1}{3}-\frac{1}{15}=\frac{5-1}{15}=\frac{4}{15}\), поэтому \(\frac{1}{\frac{1}{3}-\frac{1}{15}}=\frac{15}{4}\).
- \(\frac{1}{125}+\frac{1}{75}=\frac{75+125}{125\cdot75}=\frac{200}{9375}=\frac{8}{375}\), поэтому \(\frac{1}{\frac{1}{125}+\frac{1}{75}}=\frac{375}{8}\).
- \(\frac{1}{24}-\frac{1}{72}=\frac{72-24}{24\cdot72}=\frac{48}{1728}=\frac{1}{36}\), поэтому \(\frac{1}{\frac{1}{24}-\frac{1}{72}}=36\).
