11 and 15 Average

11 and 15 average provides the comprehensive information about what is the average of 11 and 15, and how it is being calculated mathematically. To calculate the average, the given quantities 11 and 15 can be of any physical quantity but both should have been expressed in the same measurement units.

11 and 15 average:
= (11 + 15)/2,
= 26/2,
= 13

Hence,
the average of 11 and 15 is equal to 13

where,
11 and 15 physical quantities in same measurement units,
26 is the sum of quantities,
2 is the total number of quantities,
13 is the average of 11 and 15

The step-by-step work shows how to find what is the average of 11 and 15. The solution for 11 and 15 average is same for all the following queries but have to append the measurement units based on the measurement units of physical quantities being measured.

Solved Example:
what is the average of 11 and 15?

step 1 Address the input parameters and observe what to be found:
Input values:
Quantity A = 11
Quantity B = 15

What to be found:
Find the average of 11 and 15

step 2 Find the sum of quantities 11 and 15.
11 + 15 = 26

step 3 Find how many number of inputs:
The calculation involves two quantities 11 and 15, so the number of quantities is 2.

step 4 To find the average of 11 and 15, divide the sum of quantities 26 by the total number of quantities 2:
= 26/2
= 13
(11 + 15)/2 = 13

Hence,
13 is the average of 11 and 15.
