📚 What is a Numerator?
The numerator is the top number in a fraction. It represents how many parts of a whole you have. Think of it as the 'number of parts you're interested in'. For example, in the fraction $\frac{3}{4}$, the numerator is 3.
➗ What is a Denominator?
The denominator is the bottom number in a fraction. It represents the total number of equal parts that the whole is divided into. Think of it as the 'total number of parts'. For example, in the fraction $\frac{3}{4}$, the denominator is 4.

🚀 Key Takeaways
- 🔢 The numerator counts the parts you're considering.
- 🍰 The denominator tells you the total number of equal parts.
- 💡 Remembering which is which becomes easier with practice and real-world examples (like pizza slices!).
