How do you subtract fractions without alike denominators?

Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.


When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.


How are unlike fractions identified?

Unlike fractions are identified by their different denominators. For example, in the fractions ( \frac{1}{4} ) and ( \frac{2}{3} ), the denominators 4 and 3 are not the same, making them unlike fractions. This distinction is important when performing operations such as addition or subtraction, as they require a common denominator.


How is adding fractions with unlike denominators different from addig with like denominators?

Adding fractions with like denominators is straightforward, as you simply add the numerators while keeping the denominator the same. In contrast, adding fractions with unlike denominators requires finding a common denominator, which involves identifying the least common multiple of the denominators. Once a common denominator is established, you convert each fraction accordingly before adding the numerators. This extra step makes the process more complex compared to adding fractions with like denominators.


What is the word for fractions with different denominators?

Unlike. Unlike. Unlike. Unlike.
