Answer:
29/30
Step-by-step explanation:
first, we must make sure they have the same denominator! 
2/3 x 10/10 = 20/30
3/10 x 3/3  = 9/30
20/30 + 9/30 = 29/30
 
        
             
        
        
        
The answer is:  [C]:  "30%" .

Note that: "%" ; or "percent" means "out of 100" ; or "divided by 100" .
______________________________________________________
Method 1) 
15/50 = ?/ 100 ;
Look at the denominators:
50 * (what value?) = 100 ? ;  → "100 ÷ 50 = 2" ;
→ 50 * 2 = 100 ;
So:  "15/50 = (15*2)/(50*2) = "30/100" ; which is "30%" .
___________________________________________
Method 2:
___________________________________________
 "15/50" = (15÷5) / (50÷5) = 3/10 ; 
3/10 = (3*10) / (10*10) = 30/100 ; which is:  "30%" .
__________________________________________
Method 3:  (slight variation of "Method 2" above):
___________________________________________
 "15/50" = (15÷5) / (50÷5) = 3/10 ; 
3/10 = 0.3 = 0.30 = (0.30 * 100) % =  " 30% " .
