摘　　要：Arithmetical operations are fundamental in computing models. But arithmetic operations in mem- brane computing are restricted in integer field. In this paper, we present fraction arithmetic P systems for per- forming addition, subtraction, multiplication＇s division on fractions through designing the rules with priority. Some examples are given to illustrate how to compute the arith- metical fractions in these systems and show that the de- signed rules can carry out correct arithmetic computations of fractions.
