Since there are two orange for every five green... I added them together to get 7 then divided 21 by 7. That would give you 3. Now you multiply three by two to find the answer. 
Your answer should be 6. 
        
             
        
        
        
Answer:
2/3
Step-by-step explanation:
There are a total of (3+6) = 9 coins
P( dime) = dimes / total
               = 6/9
               = 2/3
 
        
                    
             
        
        
        
Sum = (-3) + (-6) = -9
Yards gained are positive, and yards lost are negative.
If you lose 3 yards on one play and 6 yards on another, you have lost a total of 9 yards.
