Substitute 12 for b and 2 for a:

$\sf{\cfrac{4}{b}+\cfrac{a}{4}}$

$\sf{\cfrac{4}{12}+\cfrac{2}{4}}$

You can reduce the fractions.

$\sf{\cfrac{1}{3}+\cfrac{1}{2}}$

Now add the fractions

$\sf{\cfrac{1*2}{3*2}+\cfrac{1*3}{2*3}}$

$\sf{\cfrac{2}{6}+\cfrac{3}{6}}$

$\sf{\cfrac{5}{6}}$

The value of the expression is 5/6.
