Consider the addition problem: 1/3 + 5/12 and the multiplication problem: (1/3) x (5/12) what is the meaning of a denominator of 3? What is the meaning of a denominator of 12?

In both the addition and multiplication problems involving fractions, the denominator provides crucial information about how the whole is divided.

### Meaning of a Denominator of 3:
For the fraction \( \frac{1}{3} \), the denominator \( 3 \) means that the whole is divided into 3 equal parts. Each part represents one-third of the whole. For example, if you have a pizza cut into 3 equal slices, one slice would represent \( \frac{1}{3} \) of the pizza.

### Meaning of a Denominator of 12:
For the fraction \( \frac{5}{12} \), the denominator \( 12 \) means that the whole is divided into 12 equal parts. Each part represents one-twelfth of the whole. So, if you had a pizza divided into 12 equal slices, each slice would represent \( \frac{1}{12} \) of the pizza. In this fraction, you have 5 such slices, which represents \( \frac{5}{12} \) of the whole pizza.

In general:
- **Denominator** = Total number of equal parts into which the whole is divided.
- **Numerator** = Number of those equal parts being considered.

### Here are 5 related questions:
1. How do you find a common denominator when adding fractions?
2. What is the result of adding \( \frac{1}{3} + \frac{5}{12} \)?
3. How does the multiplication of fractions differ from their addition?
4. What happens when two fractions have the same denominator?
5. Can you explain why multiplying fractions results in a smaller number in most cases?

**Tip:** When adding fractions, always ensure the denominators are the same before combining the numerators.
