Let's call the mystery number ' W ' (for "which number").

You said that                2%  of  W  is  0.005

                                    0.02  x  W  =  0.005

Divide each side by  0.02 :       W  =  0.005 / 0.02  =  0.25 .

        2%  of  0.25  is  0.005 . 
    
We set up an equation: 0.005/ ?= 2/100

Cross multiply: 2*?= 0.005*100
⇒ ?= 0.005*100/2= 0.25

2% of 0.25 is 0.005.
