➕ Topic Summary
Adding fractions with the same denominator is like adding slices of the same-sized pizza. The denominator (the bottom number) tells you how many total slices are in the pizza, and the numerator (the top number) tells you how many slices you have. When the denominators are the same, you simply add the numerators and keep the denominator the same!
For example, if you have $\frac{1}{4}$ of a pizza and your friend gives you $\frac{2}{4}$ of a pizza, you now have $\frac{1+2}{4} = \frac{3}{4}$ of the pizza. Easy peasy!
