Tính nhanh:

\(\frac{\frac{1}{4}+\frac{1}{24}+\frac{1}{124}}{\frac{3}{4}+\frac{3}{24}+\frac{3}{124}}+\frac{\frac{2}{7}+\frac{2}{17}+\frac{2}{127}}{\frac{3}{7}+\frac{3}{17}+\frac{3}{127}}\)

giúp e với, ko giúp là e chết liền đây này, huhu

\(\frac{\frac{1}{4}+\frac{1}{24}+\frac{1}{124}}{\frac{3}{4}+\frac{3}{24}+\frac{3}{124}}\) + \(\frac{\frac{2}{7}+\frac{2}{17}+\frac{2}{127}}{\frac{3}{7}+\frac{3}{17}+\frac{3}{127}}\)

= \(\frac{\frac{1}{4}+\frac{1}{24}+\frac{1}{124}}{3.\left(\frac{1}{4}+\frac{1}{24}+\frac{1}{124}\right)}\) + \(\frac{2.\left(\frac{1}{7}+\frac{1}{17}+\frac{1}{127}\right)}{3.\left(\frac{1}{7}+\frac{1}{17}+\frac{1}{127}\right)}\)

= \(\frac{1}{3}\) + \(\frac{2}{3}\) = 1
