1. **Problem:** explain the fraction $\frac{2}{4}$ using a pie-style picture. 2. A fraction means **part of a whole**. - The **top number** is the number of parts you have. - The **bottom number** is the total number of equal parts. 3. For $\frac{2}{4}$: $$\frac{2}{4}$$ This means you have **2 parts out of 4 equal parts**. 4. We can simplify it by dividing the top and bottom by the same number, here $2$. $$\frac{2}{4}=\frac{\cancel{2}^{1}}{\cancel{4}^{2}}=\frac{1}{2}$$ 5. So $\frac{2}{4}$ is the same as **one-half**. 6. In a pie, if you cut it into 4 equal slices and shade 2 of them, that shows $\frac{2}{4}$. 7. **Final answer:** $\frac{2}{4}=\frac{1}{2}$, which means **half a pie**.
