МатематикаВопрос:
363 a) \(\frac{5}{11} : 3\) б) \(\frac{1}{3} : 4\) в) \(\frac{20}{9} : 8\) г) \(\frac{14}{15} : 12\) д) \(\frac{56}{13} : 7\) е) \(\frac{27}{11} : 18\)
Ответ:
Решение:
- \(\frac{5}{11} : 3 = \frac{5}{11} \cdot \frac{1}{3} = \frac{5}{33}\)
- \(\frac{1}{3} : 4 = \frac{1}{3} \cdot \frac{1}{4} = \frac{1}{12}\)
- \(\frac{20}{9} : 8 = \frac{20}{9} \cdot \frac{1}{8} = \frac{20}{72} = \frac{5}{18}\)
- \(\frac{14}{15} : 12 = \frac{14}{15} \cdot \frac{1}{12} = \frac{14}{180} = \frac{7}{90}\)
- \(\frac{56}{13} : 7 = \frac{56}{13} \cdot \frac{1}{7} = \frac{56}{91} = \frac{8}{13}\)
- \(\frac{27}{11} : 18 = \frac{27}{11} \cdot \frac{1}{18} = \frac{27}{198} = \frac{3}{22}\)
