Differential and integral as well as Partial integro-differential equations (PIDE) occur naturally in various fields of science, engineering and social sciences. In this article, the Ramadan group integral transform of the convolution is used to solve such types of equations. We propose a most general form of a linear PIDE with a convolution kernel. First, the PIDE is converted to an ordinary differential equation (ODE) using Ramadan group transform (RGT). Solving this ordinary differential equation and applying inverse RGT an exact solution of the problem is obtained. Illustrative examples are considered to demonstrate the applicability and the effectiveness of the proposed RG transform of convolution for solving integral and integro- differential equations. It is observed that the RGT is a simple, more general and reliable technique for solving such equations.
