## How do you solve adding fractions?

To add fractions there are Three Simple Steps:

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

## How do you add fractions with same denominators?

Instructions for adding fractions with the same denominator

- Build each fraction (if needed) so that both denominators are equal.
- Add the numerators of the fractions.
- The new denominator will be the denominator of the built-up fractions.
- Reduce or simplify your answer, if needed. Factor the numerator.

## How do I multiply fractions?
