To determine which fraction is **not equivalent** to the others, let's simplify each fraction:

1. **$$ \frac{9}{12} $$**
   - Simplify by dividing both numerator and denominator by 3:
   - $$ \frac{9 \div 3}{12 \div 3} = \frac{3}{4} $$

2. **$$ \frac{27}{36} $$**
   - Simplify by dividing both numerator and denominator by 9:
   - $$ \frac{27 \div 9}{36 \div 9} = \frac{3}{4} $$

3. **$$ \frac{3}{4} $$**
   - This fraction is already in its simplest form:
   - $$ \frac{3}{4} $$

4. **$$ \frac{24}{32} $$**
   - Simplify by dividing both numerator and denominator by 8:
   - $$ \frac{24 \div 8}{32 \div 8} = \frac{3}{4} $$

5. **$$ \frac{12}{15} $$**
   - Simplify by dividing both numerator and denominator by 3:
   - $$ \frac{12 \div 3}{15 \div 3} = \frac{4}{5} $$

**Summary of Simplified Fractions:**
- $$ \frac{9}{12} = \frac{3}{4} $$
- $$ \frac{27}{36} = \frac{3}{4} $$
- $$ \frac{3}{4} = \frac{3}{4} $$
- $$ \frac{24}{32} = \frac{3}{4} $$
- $$ \frac{12}{15} = \frac{4}{5} $$

All fractions except **$$ \frac{12}{15} $$** simplify to **$$ \frac{3}{4} $$**.

Therefore, the fraction **$$ \frac{12}{15} $$** is **not equivalent** to the others.

**Answer:** $$ \frac{12}{15} $$
$$ \frac{12}{15} $$ is not equivalent to the other fractions.
