Пошаговое объяснение:

$1) - 9 \frac{1}{4} - 0.75 = - \frac{37}{4} - \frac{75}{100} = - \frac{925}{100} - \frac{75}{100} = \frac{ - 1000}{100} = - 10 \\ 2) - 27 - 5 \frac{9}{20} = - \frac{540}{20} - \frac{109}{20} = - \frac{649}{20} = - 32 \frac{9}{20} \\ 3) - 5.8 - 17 \frac{3}{4} = - 5 \frac{8}{10} - 17 \frac{3}{4} = - \frac{58}{10} - \frac{71}{4} = - \frac{116}{20} - \frac{355}{20} = - \frac{471}{20} = - 23 \frac{11}{20} \\ 4) - 2 \frac{3}{5} - 9.4 = - 2 \frac{3}{5} - 9 \frac{4}{10} = - \frac{13}{5} - \frac{94}{10} = - \frac{26}{10} - \frac{94}{10} = - \frac{120}{10} = - 12$
