Two masters and apprentices process a batch of parts. The number of parts made by the master is the total number of parts made by the two (5/8). If 63 parts are taken from the parts processed by the master and given to the apprentice, the ratio of the number of parts between the master and apprentice is 2:3, how many parts did the master process?
师徒二人加工一批零件，师傅做的零件数是两人共做零件的(5/8)，如果从师傅加工的零件中取出63个给徒弟，那么师徒二人零件数的比为2：3，师傅加工了多少个零件？
