Answer 1

[Thao Nhi]

\(\frac{1212}{1313}=\frac{12}{13}va\frac{2424}{2525}=\frac{24}{25}\)

\(\frac{12}{13}+\frac{1}{13}=1\)

\(\frac{24}{25}+\frac{1}{25}=1\)

vi 1/13 >1/25 nen 12/13 <24<25

--> 1212/1313 <2424/2525

Answer 2

[Huỳnh Thị Minh Huyền]

\(\frac{1212}{1313}=\frac{12}{13}\)

\(\frac{2424}{2525}=\frac{24}{25}\)

\(\frac{12}{13}và\frac{24}{25}=\frac{300}{325}và\frac{312}{325}\)

\(vì\frac{300}{325}
