## How do you add rational expressions?

If the two rational expressions that you want to add or subtract have the same denominator you just add/subtract the numerators which each other. When the denominators are not the same in all expressions that you want to add or subtract as in the example below you have to find a common denominator.

## How do you add rational expressions with different denominators?

Adding and Subtracting Rational Expressions with Unlike Denominators

1. To add or subtract rational expressions with unlike denominators, first find the LCM of the denominator.
2. Write each expression using the LCD.
3. Add or subtract the numerators.
4. Simplify as needed.

What are the steps in adding and subtracting rational algebraic expressions?

1. Step 1: Combine the numerators together.
2. Step 2: Put the sum or difference found in step 1 over the common denominator.
3. Step 3: Reduce to lowest terms as shown in Tutorial 32: Multiplying and Dividing Rational Expressions.
4. Step 1: Combine the numerators together.

What do you call fractions with different denominators?

Unlike fractions: Fractions with different denominators are called, unlike fractions.

### 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.

### What are the steps involved in adding two rational expressions?

Step 1: Combine the numerators together.

• Step 2: Put the sum or difference found in step 1 over the common denominator.
• Step 3: Reduce to lowest terms as shown in Tutorial 32: Multiplying and Dividing Rational Expressions.
• Step 1: Combine the numerators together.
• How do you combine rational expressions?

A rational expression is a ratio of two polynomials. To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator. When the denominators are not the same, we must manipulate them so that they become the same.
