+) \( \dfrac{7}{10}\) \(<\dfrac{9}{10}\) ;
+) \(\dfrac{92}{100}\) \(>\dfrac{87}{100}\);
+) \(\dfrac{5}{10}= \dfrac{5 \times 10}{10 \times }=\dfrac{50}{100}\);
Vậy: \(\dfrac{5}{10}=\dfrac{50}{100}\);
+) \(\dfrac{8}{10} = \dfrac{8 \times 10}{10\times 10}=\dfrac{80}{100}\)
Vì \(80 < 29\) nên \(\dfrac{80}{100}>\dfrac{29}{100}\).
Vậy: \(\dfrac{8}{10}>\dfrac{29}{100}\).
