To solve the expression \( \frac{3}{4} - \frac{7}{12} \), we first need a common denominator. The least common multiple of 4 and 12 is 12.
Next, we convert \( \frac{3}{4} \) to a fraction with a denominator of 12:
\[ \frac{3}{4} = \frac{3 \times 3}{4 \times 3} = \frac{9}{12} \]
Now we can perform the subtraction:
\[ \frac{9}{12} - \frac{7}{12} = \frac{9 - 7}{12} = \frac{2}{12} \]
We can simplify \( \frac{2}{12} \):
\[ \frac{2}{12} = \frac{1}{6} \]
Thus, the final answer can be expressed in the form requested:
\[ \frac{1}{6} = [1] [1]/[6] \]
So, the answer is:
\[ 1 \quad 1/6 \]
