You need the same denominators to add fractions because fractions represent parts of a whole, and having a common denominator ensures that you are combining equivalent parts. When the denominators are the same, you can simply add the numerators while keeping the denominator constant. This maintains the correct proportion of the total value. If the denominators are different, you must first find a common denominator to accurately sum the fractions.
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.
convert the fractions so the denominators are the same if they aren't already. then add the numerators, but keep the denominator the same.
You can represent the two fractions with one fraction with a numerator equal to the sum of the two individual numerators (with sign) and a denominator equal to just one of the two denominators.
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.

-- Find a common denominator. (It will be a number of which all three denominators are factors. The best choice is their least common multiple.) -- Change the fractions to their equivalents with the common denominator. -- Then add their numerators to get the numerator of their sum.
Find their lowest common denominator and adjust their numerators accordingly and then add them together. By dividing the sum by 2 will give you the halfway result
For adding fractions, you need to make both denominators the same, then add the numerators. In this case 5/6 and 4/6 have the sum 9/6, which can be simplified to 1 1/2 (fractions are difficult in these answer windows).

In order to add fractions, they must have the same denominators. If the fractions you wish to add do not already have the same denominators, they can be made to do so by finding the right number by which to multiply both the numerator and the denominator of each fraction. To find this number, multiply all the distinct denominators together, then multiply both the numerator and denominator of each fraction by a number found by the dividing the product of the distinct denominators by the denominator of the particular fraction concerned. All the fractions will then have the same denominator. Add the numerators of such fractions together to find the numerator of the sum; its denominator will be the one common to all the fractions.
