Задание 4: Сократите дроби.

Сократим каждую дробь, разделив числитель и знаменатель на их наибольший общий делитель: * а) \(\frac{14}{21} = \frac{14 \div 7}{21 \div 7} = \frac{2}{3}\) * а) \(\frac{12}{30} = \frac{12 \div 6}{30 \div 6} = \frac{2}{5}\) * а) \(\frac{24}{60} = \frac{24 \div 12}{60 \div 12} = \frac{2}{5}\) * а) \(\frac{35}{105} = \frac{35 \div 35}{105 \div 35} = \frac{1}{3}\) * б) \(\frac{55}{77} = \frac{55 \div 11}{77 \div 11} = \frac{5}{7}\) * б) \(\frac{81}{270} = \frac{81 \div 27}{270 \div 27} = \frac{3}{10}\) * б) \(\frac{75}{450} = \frac{75 \div 75}{450 \div 75} = \frac{1}{6}\) * б) \(\frac{135}{180} = \frac{135 \div 45}{180 \div 45} = \frac{3}{4}\) * в) \(\frac{140}{210} = \frac{140 \div 70}{210 \div 70} = \frac{2}{3}\) * в) \(\frac{105}{165} = \frac{105 \div 15}{165 \div 15} = \frac{7}{11}\) * в) \(\frac{144}{360} = \frac{144 \div 72}{360 \div 72} = \frac{2}{5}\) * в) \(\frac{240}{560} = \frac{240 \div 80}{560 \div 80} = \frac{3}{7}\) * г) \(\frac{30}{150} = \frac{30 \div 30}{150 \div 30} = \frac{1}{5}\) * г) \(\frac{80}{200} = \frac{80 \div 40}{200 \div 40} = \frac{2}{5}\) * г) \(\frac{21}{36} = \frac{21 \div 3}{36 \div 3} = \frac{7}{12}\) * г) \(\frac{81}{108} = \frac{81 \div 27}{108 \div 27} = \frac{3}{4}\)
