How Do You Add Fractions With Different Denominators?

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

. Then add and simplify.

How do you add and subtract fractions with different denominators and whole numbers?

You could first convert each to an improper fraction. If they don’t have common denominators, then find a

common denominator and use it to rewrite each fraction

. Then, subtract the fractions and simplify. In this tutorial, take a look at subtracting mixed fractions with unlike denominators!

How do you add or subtract fractions with different denominators?

1. STEP ONE: Get a common denominator.
2. STEP TWO: Add or subtract the numerators.
3. STEP THREE: Simplify the result if needed. Notice that 3/27 can be simplified, since the numerator and denominator are both divisible by 3.
4. And that’s all there is to it! Final Answer:

What does it mean to add and subtract fractions?

Like fractions are fractions with the same denominator. You can add and subtract like fractions easily – simply add or subtract the numerators and write the sum over the

common denominator

.
