a) \( \frac{33}{99} = \frac{3 \cdot 11}{9 \cdot 11} = \frac{3}{9} = \frac{1 \cdot 3}{3 \cdot 3} = \frac{1}{3} \)
\( \frac{150}{125} = \frac{25 \cdot 6}{25 \cdot 5} = \frac{6}{5} \)
\( \frac{25}{100} = \frac{25 \cdot 1}{25 \cdot 4} = \frac{1}{4} \)
\( \frac{14}{210} = \frac{14 \cdot 1}{14 \cdot 15} = \frac{1}{15} \)
\( \frac{150}{1000} = \frac{15 \cdot 10}{100 \cdot 10} = \frac{15}{100} = \frac{3 \cdot 5}{20 \cdot 5} = \frac{3}{20} \)
\( \frac{1000}{2500} = \frac{10 \cdot 100}{25 \cdot 100} = \frac{10}{25} = \frac{2 \cdot 5}{5 \cdot 5} = \frac{2}{5} \)
\( \frac{264}{148} = \frac{4 \cdot 66}{4 \cdot 37} = \frac{66}{37} \)
Ответ: \( \frac{1}{3}, \frac{6}{5}, \frac{1}{4}, \frac{1}{15}, \frac{3}{20}, \frac{2}{5}, \frac{66}{37} \)
