12/25 và 25/49

Answer 1

TA CÓ 12*2=24<25, 2582=50>49

=>12/25<25/49

Answer 2

Ta có:

\(\frac{12}{25}< \frac{12}{24}=\frac{1}{2}\Rightarrow\frac{12}{25}< \frac{1}{2}\left(1\right)\)

\(\frac{25}{49}>\frac{25}{50}=\frac{1}{2}\Rightarrow\frac{25}{49}>\frac{1}{2}\left(2\right)\)

Từ \(\left(1\right)\)và\(\left(2\right)\)\(\Rightarrow\)\(\frac{12}{25}< \frac{1}{2}< \frac{25}{49}\)\(\Rightarrow\frac{12}{25}< \frac{25}{49}\)
