Adding Fractions with Like Denominators

What is the first step in adding fractions with like denominators?

• Subtract the denominators.

• Add the numerators together.

• Add the denominators together.

• Multiply the numerators.

Why do we only add the numerators when the denominators are the same?

• Because the numerators are always larger.

• Because the denominators are irrelevant.

• Because the denominators cancel each other out.

• Because we are finding the total number of pieces.

What does the denominator in a fraction represent?

• The difference between two fractions.

• The number of pieces you have.

What should you do if the denominators of two fractions are different?
