Ответ:
Блок 1: \(\frac{1}{4}-\frac{3}{25}=\frac{25}{100}-\frac{12}{100}=\frac{13}{100}\).
Блок 2: \(\frac{6}{5}:\frac{4}{11}=\frac{6}{5}\cdot\frac{11}{4}=\frac{33}{10}\).
Блок 3: \(\left(\frac{5}{22}-\frac{8}{11}\right)\cdot\frac{11}{5}=\left(\frac{5}{22}-\frac{16}{22}\right)\cdot\frac{11}{5}=-\frac{11}{22}\cdot\frac{11}{5}=-\frac{11}{10}\).
Ответ: Блок 1 — \(\frac{13}{100}\); Блок 2 — \(\frac{33}{10}\); Блок 3 — \(-\frac{11}{10}\).
