3. \( \frac{2+6}{2}= \)

First, let’s break it down step-by-step! You add \( 2 + 6 \) to get \( 8 \), and then divide that by \( 2 \). So, \( \frac{8}{2} = 4 \). Voilà! The answer is \( 4 \). Simple enough, right? Now for a fun fact: Did you know that fractions have been around since ancient Egypt? The Egyptians used a system of unit fractions, which are fractions with 1 in the numerator. They thought dividing something into equal parts was not just math; it was a way of understanding their world! How cool is that?
