Answer:

The average is 2.4.

Step-by-step explanation:

Calculating the average of some values is actually quite simple. It is also sometimes referred to as the mean, but here average specifically is discussed and calculated. To calculate any average, simply add up all of the values that you want to average, and then divide the sum of them but the number you added up. In this case, we are given the values of 2.4, 2.6, 2.7, and 2.3. Firstly, let's go ahead and simply add these number up like so: 2.4 + 2.6 + 2.7 + 2.3 = 10. Then, take the summed value, in this case, 10, and divide it by the number of values that we summed up. We added together (summed) 4 values, which were the 2.4, 2.6, 2.7, and 2.3. Again, we divide the sum of the values, 10, by the number of values, 4 to get 10/4 = 2.5. The average of these values is 2.4. Good luck!
