Adding and subtracting with unlike denominators is sometimes possible for students if they have a good conceptual understanding of the relationships between certain fractional parts and a visual tool such as a number line. This approach can be helpful in allowing students to see the relationship between the fractions and can lead to better fluency in manipulating them. The other choices are not necessarily true or are not the best approach to introducing the concept.
