3. Find \( \frac{8}{12}-\frac{5}{12} \)

To solve \( \frac{8}{12}-\frac{5}{12} \), you simply subtract the numerators since the denominators are the same. So, you take \( 8 - 5 \) which equals \( 3 \). Therefore, the result is \( \frac{3}{12} \). You can simplify \( \frac{3}{12} \) by dividing both the numerator and the denominator by their greatest common divisor, which is 3. Thus, \( \frac{3}{12} = \frac{1}{4} \). So the final answer is \( \frac{1}{4} \).
