Solve.

To solve the problem \(\frac{7}{12} - \frac{3}{8}\), we need to find a common denominator. The denominators here are 12 and 8.

The least common multiple (LCM) of 12 and 8 is 24.

Next, we convert both fractions to have a denominator of 24:

1. For \(\frac{7}{12}\):
\[
\frac{7}{12} = \frac{7 \times 2}{12 \times 2} = \frac{14}{24}
\]

2. For \(\frac{3}{8}\):
\[
\frac{3}{8} = \frac{3 \times 3}{8 \times 3} = \frac{9}{24}
\]

Now we can subtract these two fractions:
\[
\frac{14}{24} - \frac{9}{24} = \frac{14 - 9}{24} = \frac{5}{24}
\]

Thus, the answer is \(\frac{5}{24}\).

So the correct response is:
- Start fraction 5 over 24 end fraction.
