Solve the Fraction Equation: 3/2 - ? = 1/2

To solve the problem, we start with the equation:

$\frac{3}{2} - x = \frac{1}{2}$

We need to determine the value of $x$. To do this, let's isolate $x$ on one side of the equation:

Step 1: Rearrange the equation to solve for $x$:

$x = \frac{3}{2} - \frac{1}{2}$

Step 2: Perform the subtraction. Since the denominators are the same, you can directly subtract the numerators:

$x = \frac{3 - 1}{2}$

Step 3: Simplify the expression:

$x = \frac{2}{2}$

$x = 1$

Thus, the missing fraction is $1$.
