This can be solved using an example.
Let the number which is to be multipled be x
Now, x=100
So by mistake divided by 10 so 100/10 =10
But should be multiplied by 10 so 100*10 = 1000
Error % = (1000-10/1000) *100= (990/1000)*100 = 0.99*100= 99%
Hope it is useful...!

original number = N
expected = 10 N

what is done = N/10.

error =   [N/10 - 10 N]  =  - 9.9 N


% error
   = error / expected result  * 100

   =  -9.9 N / (10 N)  * 100 = - 99 %
