Solve the Fraction Subtraction: 5/6 minus 7/12

To solve the subtraction $\frac{5}{6} - \frac{7}{12}$, we need a common denominator.

Step 1: Find the least common denominator (LCD) of the two fractions.
The denominators are 6 and 12. The least common multiple of 6 and 12 is 12.

Step 2: Convert $\frac{5}{6}$ to an equivalent fraction with a denominator of 12.
We can multiply the numerator and the denominator by 2 to achieve this:
$\frac{5}{6} = \frac{5 \times 2}{6 \times 2} = \frac{10}{12}$.

Step 3: Now, subtract the fractions with a common denominator:
$\frac{10}{12} - \frac{7}{12} = \frac{10 - 7}{12} = \frac{3}{12}$.

Step 4: Simplify the result.
$\frac{3}{12}$ can be simplified by dividing both the numerator and the denominator by 3:
$\frac{3}{12} = \frac{3 \div 3}{12 \div 3} = \frac{1}{4}$.

Therefore, the solution to the problem $\frac{5}{6} - \frac{7}{12}$ is $\boxed{\frac{1}{4}}$.

From the available choices, option 4, which is $\frac{1}{4}$, is the correct answer.
