To subtract fractions, follow these steps:

1. **Find a Common Denominator:** If the fractions don’t already have the same denominator (the bottom number), find the least common multiple (LCM) of the denominators. Convert each fraction so they share this common denominator.

2. **Rewrite the Fractions:** Adjust the fractions so they have the common denominator by multiplying both the numerator (top number) and denominator of each fraction by the necessary factors.

3. **Subtract the Numerators:** Once the fractions have the same denominator, subtract the numerators while keeping the common denominator.

4. **Simplify if Possible:** If the resulting fraction can be simplified (by dividing the numerator and denominator by their greatest common factor), do so to get the fraction in its simplest form.

### Example:
Subtract \( \frac{3}{4} - \frac{1}{6} \).

1. **Find a Common Denominator:** The LCM of 4 and 6 is 12.
2. **Rewrite Fractions with Common Denominator:**
   - \( \frac{3}{4} = \frac{9}{12} \) (multiply both the top and bottom by 3)
   - \( \frac{1}{6} = \frac{2}{12} \) (multiply both the top and bottom by 2)
3. **Subtract the Numerators:** \( \frac{9 - 2}{12} = \frac{7}{12} \)
4. **Simplify if Needed:** In this case, \( \frac{7}{12} \) is already simplified.

So, \( \frac{3}{4} - \frac{1}{6} = \frac{7}{12} \).
