Step 1:
: Analyze the fractions given, which are 3 / 4 and 11 / 12.

To compare these fractions, we need to find the least common denominator (LCD) and determine if one fraction is greater than, less than, or equal to the other.

Step 2:
: Find the least common multiple (LCM) of the denominators 4 and 12.

The prime factors of 4 are 2^2 and the prime factors of 12 are 2^2 * 3. The LCM is the product of the highest powers of all prime factors, so the LCM of 4 and 12 is 2^2 * 3 = 12.

Step 3:
: To compare the fractions, we want to convert them to equivalent fractions with a common denominator of 12.

For 3 / 4, multiply both the numerator and denominator by 3 to get an equivalent fraction with a denominator of 12: (3 * 3) / (4 * 3) = 9 / 12.

Step 4:
: For 11 / 12, the fraction is already in the desired form.

Step 5:
: Compare the numerators of the equivalent fractions 9 / 12 and 11 / 12.

Since 11 is greater than 9, 11 / 12 is greater than 9 / 12, which is equivalent to 3 / 4.

Final Answer

\frac{3}{4} < \frac{11}{12}
