Answer:
(2y-4)cm
Step-by-step explanation:
In the given question we have (4y-8) divided by 2
which can be written mathematically as [tex]\frac{\left ( 4y-8 \right )cm}{2}[/tex]
Now (4y-8) is a quatity with unit cm. and the whole expression is in parentheses. Moreover, two quatity can only be added or subtracted only when their units are same. Therefore 4y and 8 must have same unit that is cm.
Therefore, [tex]\frac{\left ( 4y-8 \right )cm}{2}=(2y-4)cm[/tex] and not anything else
