Do you need a common denominator for dividing fractions?

How do you minnous fractions?

Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

Meaning of adding of dissimilar fractions?

Adding dissimilar fractions involves finding a common denominator for the fractions before adding them together. This common denominator is the least common multiple of the denominators of the fractions being added. Once the fractions have the same denominator, you can add the numerators together while keeping the denominator the same. Finally, simplify the resulting fraction if possible by reducing it to its simplest form.
