The FIFO method provides a major advantage over the weighted-average method in that: A. the calculation of equivalent units is less complex under the FIFO method. B. the FIFO method treats units in the beginning inventory as if they were started and completed during the current period. C. the FIFO method separates the work done during the current period to provide measurements of work done during the current period. D. the FIFO method considers units in the work done in the ending work-in-process inventories. E. the FIFO method more correctly computes the equivalent units of direct materials when they are added at the beginning of the production process.
