A. \[\frac{{29}}{{41}};\frac{{28}}{{41}};\frac{{29}}{{40}}\]
B. \[\frac{{29}}{{40}};\frac{{29}}{{41}};\frac{{28}}{{41}}\]
C. \[\frac{{28}}{{41}};\frac{{29}}{{41}};\frac{{29}}{{40}}\]
D. \[\frac{{28}}{{41}};\frac{{29}}{{40}};\frac{{29}}{{41}}\]
Ta có:
+) 28 < 29 nên \[\frac{{28}}{{41}} < \frac{{29}}{{41}}\]
+) 41 >40 nên \[\frac{{29}}{{41}} < \frac{{29}}{{40}}\]
Do đó \[\frac{{28}}{{41}} < \frac{{29}}{{41}} < \frac{{29}}{{40}}\]
