How to make the sum of two fractions ?
For making the sum of two fractions, we check whether the two fractions have the same denominator or not, if they have
the same denominator, we add their numerators and we place the common denominator under the sum of the two fractions;
if their denominators are not common we reduce the two fractions at the same denominator before to add the
numerators and place the commun denominator under the sum.
Example: 11/3 + 5/3 = 16/3; 8/12 + 2/12 = 10/12.
1/2 + 2/5 = 5/10 + 4/10 = 9/10.
