No but the denominators must be the same and you just add the numerators. If the denominators are different and you have to find which is greater you have to find a denominator that both numbers can multiply into. For example, 5/6 and 3/12 will be our fractions. 6 times to equals 12. Since 12 is the other denominator 3/12 stays the same. Thats the only time you can change the denominator.
