Solve the Fraction Subtraction: 3/2 - 1/2

To solve this problem, we'll follow these steps:

• Step 1: Recognize that the fractions $\frac{3}{2}$ and $\frac{1}{2}$ have a common denominator.
• Step 2: Subtract the numerators, keeping the denominator unchanged.
• Step 3: Simplify the resulting fraction if needed.

Now, let's work through each step:

Step 1: The fractions involved are $\frac{3}{2}$ and $\frac{1}{2}$, both with the denominator of 2.

Step 2: Subtract the numerators: $3 - 1 = 2$. So, the fraction becomes $\frac{2}{2}$.

Step 3: Simplify $\frac{2}{2}$. Since $\frac{2}{2} = 1$, the solution is a whole number.

Therefore, the solution to the problem is $1$. This corresponds to choice number 2.
