Answer 4

Kết quả là :

\(\frac{12}{47}>\frac{19}{77}\)

     Đáp số : \(\frac{12}{47}>\frac{19}{77}\)

Answer 5

\(\frac{12}{47}>\frac{19}{77}\)

Answer 6

\(\frac{12}{47}\)và  \(\frac{19}{77}\)

Ta có : \(\frac{12}{47}=\frac{12.77}{47.77}=\frac{924}{3619}\)   \(\left(1\right)\)

            \(\frac{19}{77}=\frac{19.47}{77\cdot47}=\frac{893}{3619}\) \(\left(2\right)\)

Answer 8

\(\frac{12}{47}=\frac{12.77}{47.77}=\frac{924}{3619};\frac{19}{77}=\frac{19.47}{77.47}=\frac{893}{3619}\)

Vì \(\frac{924}{3619}>\frac{893}{3619}\)

Nên \(\frac{12}{47}>\frac{19}{77}\)

Answer 9

\(\frac{12}{47}\)và \(\frac{19}{77}\)

Ta có : \(\frac{12}{47}=\frac{12\cdot77}{47\cdot77}=\frac{924}{3619}\); \(\frac{19}{77}=\frac{19\cdot47}{77\cdot47}=\frac{893}{3619}\)

Vì : \(\frac{924}{3619}>\frac{893}{3619}\)nên \(\frac{12}{47}>\frac{19}{77}\)
