Abstarct: Abstract The aim of this research is to study and investigate fractional differential equations with point of view of Lie groups. Using symmetries to solve equations is one of the best methods that has been given a lot of attention in recent years. To begin with, several definitions are given to explain how to calculate Lie symmetries for partial differential equations, and then the method of reduction and solution of aforementioned is presented. In the following, with the help of definitions and jurisprudence, this issue is given for approximate and fractional differential equations, and finally, fractional equations with different combinations are discussed. Also, the important concepts of conservation laws of differential equations for all types of equations have been explored in order to discuss and investigate the basic laws and their calculation methods for fractional-approximate differential equations.
