Question

What is the average of 22.10; 13.45; 25.10; 17.20; 19.10?

Answer 1

Hey!

It looks like we are talking about finding the mean. First, let's write the numbers. 
$22.10, 13.45, 25.10, 17.20, 19.10$
We have five numbers. To find the mean, we have to add all those numbers and divide the result by 5.
$\frac{22.10+ 13.45+ 25.10+ 17.20+ 19.10}{5}$
Simplify
$Mean=19.39$
We have successfully determined that the average (mean) of this set of values is 19.39.

Thanks!

Answer 2

Average = (22.10 + 13.45 + 25.10 + 17.20 + 19.10) / 5 = 96.95/5 = 19.39 <=
