May, June and July have 31, 30 and 31 days respectively. Weighting each month’s daily rainfall by its days gives the expression: (31 × 3.5 + 30 × 10 + 31 × 8.7) / 92.

    1. Because the three months have differing lengths—May has 31 days, June has 30 days and July has 31 days—the daily averages cannot be simply added and divided by 3. Each average must be weighted by the number of days in that month. Summing these products and dividing by the total of 92 days gives the combined average expression: (31 × 3.5 + 30 × 10 + 31 × 8.7) / 92.
