### Addition of fractions with the same denominator

The addition of two fractions with the same denominators can be thought of as steps on the number line.

To add $$\dfrac{3}{8} \text{and} \dfrac{4}{8}$$ we start at $$\dfrac{3}{8}$$ and take a step of $$\dfrac{4}{8} \text{to get} \dfrac{7}{8}$$.

We write $$\dfrac{3}{8} + \dfrac{4}{8} = \dfrac{7}{8}$$.
