4 and 9 Average

4 and 9 average provides the comprehensive information about what is the average of 4 and 9, and how it is being calculated mathematically. To calculate the average, the given quantities 4 and 9 can be of any physical quantity but both should have been expressed in the same measurement units.

4 and 9 average:
= (4 + 9)/2,
= 13/2,
= 6.5

Hence,
the average of 4 and 9 is equal to 6.5

where,
4 and 9 physical quantities in same measurement units,
13 is the sum of quantities,
2 is the total number of quantities,
6.5 is the average of 4 and 9

The step-by-step work shows how to find what is the average of 4 and 9. The solution for 4 and 9 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 4 and 9?

step 1 Address the input parameters and observe what to be found:
Input values:
Quantity A = 4
Quantity B = 9

What to be found:
Find the average of 4 and 9

step 2 Find the sum of quantities 4 and 9.
4 + 9 = 13

step 3 Find how many number of inputs:
The calculation involves two quantities 4 and 9, so the number of quantities is 2.

step 4 To find the average of 4 and 9, divide the sum of quantities 13 by the total number of quantities 2:
= 13/2
= 6.5
(4 + 9)/2 = 6.5

Hence,
6.5 is the average of 4 and 9.
