Not at all.
(1/2) + (1/2) = 1
(1/5) + (8/15) + (4/15) = 1
(1/3) + (2/3) + (1/4) + (1/6) + (7/12) = 2

No - one half plus one half equals one.
First add all the fractions together. Then, divide this sum by the total number of fractions that were in the set. This quotient is your average fraction.
The two fractions are -181/2 and 191/2.
To make a fraction magic square, start by filling in the grid with fractions so that each row, column, and diagonal has the same sum. Use different fractions that have the same sum but different denominators to create a variety of solutions. You can also adjust the value of the fractions to make the magic square more challenging.
The sum of two fractions will only be a whole number if the fractions have a common denominator. When the denominators are different, the sum will be a fraction with a different denominator, making it impossible to be a whole number. Thus, estimating the sum of two fractions will generally result in a fraction, not a whole number.
