摘要：By employing classical Watson's and Whipple's $_3F_{2}$-summation theorems, recently Liu, et al. have obtained a few Ramanujan type series for $\frac{1}{\pi}$ and deduced twelve interesting formulas for $\frac{1}{\pi}$. The aim of this short research paper is to point out that these twelve interesting formulas for $\frac{1}{\pi}$ can be easily obtained by employing classical Gauss's summation theorem.
