so sánh

\(\frac{1313}{9191}\) và \(\frac{1111}{7373}\)

Answer 1

\(\frac{1313}{9191}=\frac{1313:1313}{9191:1313}=\frac{1}{7}=\frac{73}{511}\)

\(\frac{1111}{7373}=\frac{1111:101}{7373:101}=\frac{11}{73}=\frac{77}{511}\)

Vì \(\frac{73}{511}< \frac{77}{511}\) nên \(\frac{1313}{9191}< \frac{1111}{7373}\).
