what is unlike fraction

Unlike fractions are fractions that have different denominators. For example, 2/3, 4/9, 6/67, and 9/89 are unlike fractions because their denominators have different values. Unlike fractions are also known as dissimilar fractions. It is not easy to add or subtract unlike fractions directly because of their different denominators. To perform arithmetic operations like addition and subtraction, we have to convert the unlike fractions into like fractions first. Like fractions are fractions that have the same denominator. For example, 1/2 and 3/2 are like fractions because they have the same denominator of 2. To convert unlike fractions to like fractions, we need to find the lowest common multiple (LCM) of the denominators first and then calculate their equivalent fractions with the same denominator.
