Давай сократим каждую дробь.

a)

1) \(\frac{33}{99} = \frac{33:33}{99:33} = \frac{1}{3}\)

2) \(\frac{150}{125} = \frac{150:25}{125:25} = \frac{6}{5}\)

3) \(\frac{25}{100} = \frac{25:25}{100:25} = \frac{1}{4}\)

4) \(\frac{14}{210} = \frac{14:14}{210:14} = \frac{1}{15}\)

5) \(\frac{150}{1000} = \frac{150:50}{1000:50} = \frac{3}{20}\)

6) \(\frac{1000}{2500} = \frac{1000:500}{2500:500} = \frac{2}{5}\)

7) \(\frac{264}{148} = \frac{264:4}{148:4} = \frac{66}{37}\)

б)

1) \(\frac{45}{630} = \frac{45:45}{630:45} = \frac{1}{14}\)

2) \(\frac{30}{64} = \frac{30:2}{64:2} = \frac{15}{32}\)

3) \(\frac{125}{500} = \frac{125:125}{500:125} = \frac{1}{4}\)

4) \(\frac{7}{217} = \frac{7:7}{217:7} = \frac{1}{31}\)

5) \(\frac{12}{600} = \frac{12:12}{600:12} = \frac{1}{50}\)

6) \(\frac{75}{300} = \frac{75:75}{300:75} = \frac{1}{4}\)

7) \(\frac{140}{210} = \frac{140:70}{210:70} = \frac{2}{3}\)

Ответ: a) \(\frac{1}{3}, \frac{6}{5}, \frac{1}{4}, \frac{1}{15}, \frac{3}{20}, \frac{2}{5}, \frac{66}{37}\) ; б) \(\frac{1}{14}, \frac{15}{32}, \frac{1}{4}, \frac{1}{31}, \frac{1}{50}, \frac{1}{4}, \frac{2}{3}\)

Ты молодец! У тебя всё получится!
