Sum of Fractions Calculator

As we all know, the addition of fractions is not the same as the addition of integers. You cannot add two fractions directly. It is necessary to consider whether the denominators are the same. If the denominators are not the same, first convert the denominator to the same number. When the denominator changes, the numerator also changes accordingly. Therefore, a free online sum of fractions calculator is necessary.
