Final answer:
The question requests the calculation of allocation ratios for four departments using the direct method, but data provided is insufficient for calculation.
Step-by-step explanation:
The question pertains to the calculation of allocation ratios using the direct method in what seems to be a cost accounting or production situation. However, the data provided in the question is insufficient to perform the calculation, and the context is not clear. Information such as the total costs to be allocated and specific details regarding the basis for allocation (e.g., square footage, direct labor hours, machine hours, etc.) to the four departments would be necessary to give a precise answer. Assuming 150,000 relates to total costs to be allocated or total units of allocation basis, the actual ratios would depend on individual department data which has not been provided.
