6 and 15 Average

6 and 15 average provides the comprehensive information about what is the average of 6 and 15, and how it is being calculated mathematically. To calculate the average, the given quantities 6 and 15 can be of any physical quantity but both should have been expressed in the same measurement units.

6 and 15 average:
= (6 + 15)/2,
= 21/2,
= 10.5

Hence,
the average of 6 and 15 is equal to 10.5

where,
6 and 15 physical quantities in same measurement units,
21 is the sum of quantities,
2 is the total number of quantities,
10.5 is the average of 6 and 15

The step-by-step work shows how to find what is the average of 6 and 15. The solution for 6 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 6 and 15?

step 1 Address the input parameters and observe what to be found:
Input values:
Quantity A = 6
Quantity B = 15

What to be found:
Find the average of 6 and 15

step 2 Find the sum of quantities 6 and 15.
6 + 15 = 21

step 3 Find how many number of inputs:
The calculation involves two quantities 6 and 15, so the number of quantities is 2.

step 4 To find the average of 6 and 15, divide the sum of quantities 21 by the total number of quantities 2:
= 21/2
= 10.5
(6 + 15)/2 = 10.5

Hence,
10.5 is the average of 6 and 15.
