a)\(\frac{11}{54}=\frac{11.2}{54.2}=\frac{22}{108}\)
Vì 108>37 nên: \(\frac{22}{108}< \frac{22}{37}\Rightarrow\frac{11}{54}< \frac{22}{37}\)
b)\(\frac{24}{49}=\frac{24.23}{49.23}=\frac{552}{1127};\frac{23}{45}=\frac{23.24}{45.24}=\frac{552}{1080}\)
Vì 1127>1080 nên: \(\frac{552}{1127}< \frac{552}{1080}\Rightarrow\frac{24}{49}< \frac{23}{45}\)
a/ Ta có: \(\frac{22}{37}=\frac{11}{37}+\frac{11}{37}\)
Mà \(\frac{11}{37}>\frac{11}{54}\)
=>\(\frac{22}{37}>\frac{11}{54}\)
a)Ta có 11/54=22/108
Mà 108>37=>22/37>22/108
Hay 11/54<22/37
b)Vì 24*45=24*(49-4)=24*49-24*4
23*49=(24-1)*49=24*49-49
Vì 49<24*4=>24*49-49>24*49-24*4=>24/49>23/45
