9/2-34

To solve the expression \( \frac{9}{2} - 34 \), you first convert \( 34 \) into a fraction with a denominator of \( 2 \).

So, \( 34 = \frac{34 \times 2}{2} = \frac{68}{2} \).

Now, the expression becomes:

\[ \frac{9}{2} - \frac{68}{2} = \frac{9 - 68}{2} = \frac{-59}{2} \]

Thus, \( \frac{9}{2} - 34 = -\frac{59}{2} \) or in decimal form, it is \( -29.5 \).
