Maybe it the mixed number form. 2 1/2?
To find the average: the sum of the values/number of values
=250+310+275+195/4
=257.5
You don't simplify rational numbers, but sometimes you can simplify a fraction.
The way to do that is to divide the top and bottom by their greatest common factor.
The greatest common factor of 57 and 69 is 3 . When you divide the top and
bottom by 3 , you have 19/23 . That's the simplest form of that particular fraction.
