#v/8#

First of all, numerically, look at #5/40#.

#5/40# has as the greatest common factor #5#, so

#5/5=1 and 40/5=8#

So #5/40 = 1/8#

For the variables, to divide exponents, you subtract the denominator exp from the numerator exp. So it will be

#v^(5-4)=v and w^(2-2)=w^0#

and any number to the power of #0# is equal to #1#.
