Answer:
\(\frac{1}{2}\)
Step-by-step explanation:
We are given that an expression
\(\frac{1}{2}a-\frac{1}{2}\)
We have to find out the factor of coefficient of the variable.
In order to find out the factor we will factorize the each term in the given expression
\(\frac{1}{2}a-\frac{1}{2}\)
\(\frac{1}{2}\times a-\frac{1}{2}\)
\(\frac{1}{2}(a-1)\)
Hence, factor of coefficient of variable is \(\frac{1}{2}\)
