To solve for \( f \) in the equation:

\[
\frac{f}{2} - 1.68 = 1.38
\]

1. **Add \( 1.68 \) to both sides** to isolate the term with \( f \) on the left side:

   \[
   \frac{f}{2} = 1.38 + 1.68
   \]

   \[
   \frac{f}{2} = 3.06
   \]

2. **Multiply both sides by 2** to solve for \( f \):

   \[
   f = 3.06 \times 2
   \]

   \[
   f = 6.12
   \]

So, \( f = 6.12 \).
