Final answer:
The expression simplifies to k+2 and the value of a/b is 1.
Step-by-step explanation:
The expression \(rac{{4k+8}}{{4}}\) simplifies to an expression of the form \(ak+b\) where \(a\) and \(b\) are integers. To find \(rac{{a}}{{b}}\), we need to simplify the expression.
When we divide the numerator \(4k+8\) by the denominator \(4\), we get \(k+2\). Therefore, the expression simplifies to \(k+2\).
As a result, the value of \(rac{{a}}{{b}}\) is 1, since \(a\) and \(b\) are both equal to 1 in this case.
