Literal question
Now consider the different months of the year. Write 100 in the month or months in which the sales of your business are highest. Then for the other months, write the percentage of the best month's sales that you would typically get in that month. E.g. if your best month of sales is February, write 100 in February. Then if you typically sell only half this much in March, write 50 for March. Write zero for months you don't sell anything.
