15 and 20 Average

15 and 20 average provides the comprehensive information about what is the average of 15 and 20, and how it is being calculated mathematically. To calculate the average, the given quantities 15 and 20 can be of any physical quantity but both should have been expressed in the same measurement units.

15 and 20 average:
= (15 + 20)/2,
= 35/2,
= 17.5

Hence,
the average of 15 and 20 is equal to 17.5

where,
15 and 20 physical quantities in same measurement units,
35 is the sum of quantities,
2 is the total number of quantities,
17.5 is the average of 15 and 20

The step-by-step work shows how to find what is the average of 15 and 20. The solution for 15 and 20 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 15 and 20?

step 1 Address the input parameters and observe what to be found:
Input values:
Quantity A = 15
Quantity B = 20

What to be found:
Find the average of 15 and 20

step 2 Find the sum of quantities 15 and 20.
15 + 20 = 35

step 3 Find how many number of inputs:
The calculation involves two quantities 15 and 20, so the number of quantities is 2.

step 4 To find the average of 15 and 20, divide the sum of quantities 35 by the total number of quantities 2:
= 35/2
= 17.5
(15 + 20)/2 = 17.5

Hence,
17.5 is the average of 15 and 20.
