\(\frac{4}{5}=\frac{4\times9}{5\times9}=\frac{36}{45}\)
\(\frac{10}{9}=\frac{10\times5}{9\times5}=\frac{50}{45}\)
Vì: \(\frac{36}{45}< \frac{50}{45}\)
Nên: \(\frac{4}{5}< \frac{10}{9}\)
Cách 1 :
4/5 = 36/45
10/9 = 50/45
vì 36 < 50 ---> 36/45 < 50/45
---> 4/5 < 10/9
Cách 2 :
Ta có 1 > 4/5
Cũng có : 1 < 10/9
---> 4/5 < 10/9
