Rút gọn phân số

77/176; 232323/474747; 376376/159159; 9×8×5/24×15

Answer 1

     \(\frac{77}{176}=\frac{77:11}{176:11}=\frac{7}{16}\)                              ;                               \(\frac{232323}{474747}=\frac{232323:10101}{474747:10101}=\frac{23}{47}\)

       \(\frac{376376}{159159}=\frac{376376:1001}{159159:1001}=\frac{376}{159}\)                ;                    \(\frac{9\cdot8\cdot5}{24\cdot15}=\frac{9\cdot8\cdot5}{8\cdot3\cdot3\cdot5}=\frac{9\cdot8\cdot5}{8\cdot9\cdot5}=1\)

Answer 2

\(\frac{9.8.5}{24.15}\)

\(=\frac{9.8.5}{8.3.3.5}\)
