Điền lớn bé bằng

\(\frac{5}{8}\) < \(\frac{7}{8}\)

\(\frac{9}{{14}}\) > \(\frac{6}{{14}}\)

\(\frac{3}{4}\) < \(\frac{5}{6}\)

Giải thích

\(\frac{3}{4} = \frac{{3 \times 3}}{{4 \times 3}} = \frac{9}{{12}}\)

\(\frac{5}{6} = \frac{{5 \times 2}}{{6 \times 2}} = \frac{{10}}{{12}}\)

Vì 9 < 10 nên \(\frac{9}{{12}} < \frac{{10}}{{12}}\) hay \(\frac{3}{4}\) < \(\frac{5}{6}\)

\(\frac{7}{{10}}\) > \(\frac{2}{3}\)

Giải thích

\(\frac{7}{{10}} = \frac{{7 \times 3}}{{10 \times 3}} = \frac{{21}}{{30}}\)

\(\frac{2}{3} = \frac{{2 \times 10}}{{3 \times 10}} = \frac{{20}}{{30}}\)

Vì 21 > 20 nên \(\frac{{21}}{{30}} > \frac{{20}}{{30}}\) hay \(\frac{7}{{10}}\) > \(\frac{2}{3}\)
