Catalina started with $$ 6 \frac{3}{4} $$ cups of flour. She used $$ 2 \frac{1}{2} $$ cups in one recipe and $$ 2 \frac{1}{4} $$ cups in another. To find out how much flour she has left, follow these steps:

1. **Convert mixed numbers to improper fractions:**
   - $$ 2 \frac{1}{2} = \frac{5}{2} $$
   - $$ 2 \frac{1}{4} = \frac{9}{4} $$
   - $$ 6 \frac{3}{4} = \frac{27}{4} $$

2. **Calculate the total amount of flour used:**
   $$
   \frac{5}{2} + \frac{9}{4} = \frac{10}{4} + \frac{9}{4} = \frac{19}{4} = 4 \frac{3}{4}
   $$

3. **Subtract the used flour from the initial amount:**
   $$
   6 \frac{3}{4} - 4 \frac{3}{4} = 2 \frac{0}{4} = 2
   $$

**Answer:** Catalina has **2 cups** of flour left.
Catalina has 2 cups of flour left.
