# 70 and 90 Average 70 and 90 average provides the comprehensive information about what is the average of 70 and 90, and how it is being calculated mathematically. To calculate the average, the given quantities 70 and 90 can be of any physical quantity but both should have been expressed in the same measurement units.

70 and 90 average:
= (70 + 90)/2,
= 160/2,
= 80

Hence,
the average of 70 and 90 is equal to 80

where,
70 and 90 physical quantities in same measurement units,
160 is the sum of quantities,
2 is the total number of quantities,
80 is the average of 70 and 90

For values other than 70 and 90, use this below tool:

Solved Example:
what is the average of 70 and 90?

step 1 Address the input parameters and observe what to be found:
Input values:
Quantity A = 70
Quantity B = 90

What to be found:
Find the average of 70 and 90

step 2 Find the sum of quantities 70 and 90.
70 + 90 = 160

step 3 Find how many number of inputs:
The calculation involves two quantities 70 and 90, so the number of quantities is 2.

step 4 To find the average of 70 and 90, divide the sum of quantities 160 by the total number of quantities 2:
= 160/2
= 80
(70 + 90)/2 = 80

Hence,
80 is the average of 70 and 90.
