To answer this question, we have that:
a = 7
b = 56
If we have that the expression is:
[tex]\frac{b}{7+a}[/tex]Then we have to substitute the values of, b, and, a, into the expression as follows:
[tex]b=56,a=7\Rightarrow\frac{56}{7+7}=\frac{56}{14}=4[/tex]Therefore, the result of the evaluation of the expression when a = 7 and b = 56 is 4.
