Ta có: \(\frac{1}{3}=\frac{13}{39}\)
Thấy: \(\frac{13}{38}>\frac{13}{39}\)
Vậy: \(\frac{1}{3}< \frac{13}{38}\)
Ta có :
\(\frac{13}{38}>\frac{13}{39}\) mà \(\frac{13}{39}=1\) nên \(\frac{13}{38}>1\)
Vậy \(\frac{13}{38}>1\)
Ta có:
\(\frac{13}{38}>\frac{13}{39}=\frac{1}{3}\)
Vậy \(\frac{13}{38}>\frac{1}{3}\)
