In the case that the given fractions are dissimilar, how shall we make them similar being the only way to proceed to addition or subtraction of fractions?

• Add the denominators together. Whatever is the sum, that will be the denominator for both fractions.

• Just choose either of the denominator from both fractions that you wanted as new denominator before you proceed to adding and subtracting the numerators.

• Simply find LCD and use such LCD as the new denominator for both fractions. Then find equivalent fractions for each given.

• All of the above.
