$\frac{1}{2}(a-1)$

Step-by-step explanation:

We have to factor out a coefficient that is common to both the terms.

Looking at the problem:

$\frac{1}{2}a-\frac{1}{2}$

We can see that we can take out $\frac{1}{2}$ from both the terms. Taking out, or taking common means to divide:

$\frac{\frac{1}{2}a}{\frac{1}{2}}=a$

and

$\frac{\frac{1}{2}}{\frac{1}{2}}=1$

Thus, we have:

$\frac{1}{2}a-\frac{1}{2}\\=\frac{1}{2}(a-1)$

This is the simplified form.
