How do you add two fractions together?

To add fractions there are Three Simple Steps:

1. Step 1: Make sure the bottom numbers (the denominators) are the same.
2. Step 2: Add the top numbers (the numerators), put that answer over the denominator.
3. Step 3: Simplify the fraction (if possible)

How do you add and subtract fractions with different denominators?

Adding and Subtracting Fractions With Different Denominators

1. Find the LCD.
2. Convert each fraction to an equivalent form with the LCD as the denominator.
3. Add or subtract the fractions.
4. Write the result in simplified form.

How do you add two fractions?

The easiest and simplest way to convert the two fractions to equivalent fractions with the same denominators is to multiply the numerator and denominator of each fraction by the other fraction’s denominator. Once the two fractions have the same denominator, we can add the numerators together.

How do you find the least common denominator of two fractions?

One way to find the least common denominator (LCD) of two or more fractions is by listing the factors of each denominator, which are all of the whole numbers that divide evenly into that number. Then, identify the greatest common factor between the two denominators.

What are the steps to add unlike fractions?

Steps for adding unlike denominators are explained below. Find the least common denominator of the fractions. Find a common denominator. Build each fraction so that both the denominators are equal. Add the numerators of the fraction. Simplify the fraction if possible.

Can you cross-cancel when adding fractions?

However, when multiplying or even dividing fractions , this is no longer a concern. Instead, you multiply the two numbers in the numerators and multiply the two numbers in the denominators. To save work later, always remember to check if you can cross – cancel .
