Assuming beginning work in process is zero, the equivalent units of production computed using fifo versus weighted average will have the following relationship:
1. FIFO equivalent units will be greater than weighted-average equivalent units.
2. FIFO equivalent units will be less than weighted-average equivalent units.
3. Weighted-average equivalent units are always greater than fifo equivalent units.
4. Weighted-average equivalent units will be equal to fifo equivalent units.

Equivalent units of production is been applied to the work-in-process inventory when an accounting period comes to an end. It can be regarded as expression that gives amount of work done which was recorded by a manufacturer over a units of output which was partially completed after an accounting period. For instance, if there are 100 units that are in process, then 40% of processing cost is expended , then we can say there are 40 equivalent units of production. It should be noted that the if beginning work in process is zero, the equivalent units of production computed using fifo versus weighted average will have a relationship in such a way that Weighted-average equivalent units will be equal to FIFO equivalent units.
