On average, how many stamps has Jane collected per month if she has collected 132 stamps in a year?

To determine the average number of stamps Jane has collected per month, we need to divide the total number of stamps she has collected in a year by the number of months in a year, which is 12.

Jane has collected a total of 132 stamps. By performing the following calculation:

132 stamps ÷ 12 months = 11 stamps per month.

This indicates that, on average, Jane has been collecting 11 stamps each month. This mathematical process of finding an average involves understanding the relationship between total quantity and time period, where the total is distributed across the months. Thus, the calculation supports the conclusion that Jane collects an average of 11 stamps per month.
