You can put this solution on YOUR website!

1%2F5 of a number n is %281%2F5%29n or n%2F5
when 2 is added to n%2F5 we have n%2F5%2B2 and that is equal to 3.2
so, your equation will be: n%2F5%2B2=3.2 ...now solve for n

n%2F5=3.2-2
n%2F5=1.2
n=1.2%2A5
n=6.0
check:
if n=6 than n%2F5=6%2F5=1.2
if you add 2 to it you got 1.2%2B2=3.2 which was given
