124/129=1-5/129
456/461=1-5/461
Vì 5/129>5/461=>124/129<456/461
Ta có :
\(1-\frac{124}{129}=\frac{5}{129}\)
\(1-\frac{456}{461}=\frac{5}{461}\)
Vì : \(\frac{5}{129}>\frac{5}{461}\)nên \(\frac{124}{129}< \frac{456}{461}\)
Đ/S :...
\(\frac{124}{129}< \frac{456}{461}\)
\(\frac{124}{129}\)và \(\frac{456}{461}\)
Ta có :
\(1=\frac{124}{129}+\frac{5}{129}\)
\(1=\frac{456}{461}+\frac{5}{461}\)
Vì \(\frac{5}{129}>\frac{5}{461}\)\(\Rightarrow\frac{124}{129}< \frac{456}{461}\)
