9 and 15 Average
9 and 15 average provides the comprehensive information about what is the average of 9 and 15, and how it is being calculated mathematically. To calculate the average, the given quantities 9 and 15 can be of any physical quantity but both should have been expressed in the same measurement units.
9 and 15 average:
= (9 + 15)/2,
= 24/2,
= 12
Hence,
the average of 9 and 15 is equal to 12
where,
9 and 15 physical quantities in same measurement units,
24 is the sum of quantities,
2 is the total number of quantities,
12 is the average of 9 and 15

Solved Example:
what is the average of 9 and 15?
step 1 Address the input parameters and observe what to be found:
Input values:
Quantity A = 9
Quantity B = 15
What to be found:
Find the average of 9 and 15
step 2 Find the sum of quantities 9 and 15.
9 + 15 = 24
step 3 Find how many number of inputs:
The calculation involves two quantities 9 and 15, so the number of quantities is 2.
step 4 To find the average of 9 and 15, divide the sum of quantities 24 by the total number of quantities 2:
= 24/2
= 12
(9 + 15)/2 = 12
Hence,
12 is the average of 9 and 15.
