The rainfall for three months was 4.6 inches, 3.5 inches, and 4.2 inches. What was the average monthly rainfall during that time?

4.6 + 4.2 + 3.5= YOUR Answer divided by 3

To find the average monthly rainfall, you need to add up the rainfall for all three months and then divide by the total number of months.

In this case, the rainfall for the three months is 4.6 inches, 3.5 inches, and 4.2 inches.

To calculate the average, add up these three amounts:

4.6 + 3.5 + 4.2 = 12.3 inches

Then, divide the total by the number of months (which is 3):

12.3 / 3 = 4.1 inches

Therefore, the average monthly rainfall during that time is 4.1 inches.
