__________________________________________________
Explanation:
____________________________________________
Given:  2/100  +  3/10  =  _?__  ??
____________________________________________
    Note:  3/10 = ? / 100  ;
_____________________________________  
           10 * 10  = 100 ;

so:     3/10 = (3*10) / (10*10) = 30/100 ;
_____________________________________
So;   2/100 + 3/10  =  2/100 + 30/100 = 32/100 ;
________________________________________
We have:  "32/100" ; which can be written in "decimal form" ;
_________________________________________
       "32/100"  =  32 ÷ 100  = 0.32 ;
_________________________________________
Or, "32/100" can be simplified further, in "fraction form" ;
_________________________________________
       "32/100" = (32÷8) / (100÷8)  = 4/25  ;
______________________________________________
The answer:  "0.25" ; or;  "4/25" .
