To find the average of three numbers, you add them together and then divide by the total number of values. In this case, the sum of 657, 890, and 1240 is 2787. Dividing this sum by 3 (the total number of values) gives an average of 929. Therefore, the average of 657, 890, and 1240 is 929.

Well, darling, to find the average of those numbers, you add them up and then divide by how many there are. So, 657 + 890 + 1240 equals 2787. Divide that by 3 (because there are 3 numbers) and you get an average of 929. And there you have it, sweet cheeks.
