Đáp án:
Giải thích các bước giải:
7/10 < 9/10
92/100 >87/100
5/10=50/100
8/10>29/100
\[\begin{array}{l}
+ )\,\,\,\frac{7}{{10}} < \frac{9}{{10}}\,\,\,\left( {do\,\,7 < 9} \right)\\ + )\,\,\frac{{92}}{{100}} > \frac{{87}}{{100}}\,\,\,\left( {do\,\,92 > 87} \right)\\
+ )\,\,\frac{5}{{10}} = \frac{1}{2};\,\,\,\,\frac{{50}}{{100}} = \frac{1}{2}\\
\Rightarrow \frac{5}{{10}} = \frac{{50}}{{100}}.\\
+ )\,\,\frac{8}{{10}} = \frac{{80}}{{100}} > \frac{{29}}{{100}}\\
\Rightarrow \frac{8}{{10}} > \frac{{29}}{{100}}.
\end{array}\]
