First add the whole numbers. 
Then find the LCM (least common multiple) of 3 and 2, which are the denominators of both fractions. In this case, the LCM of 3 and 2 are 6. 
As you can see in the photo, I multiplied a number than can result in 6 in both denominators. Then multiply that same number to the numerators. 
Finally, add 21+2, but keep the denominator as 6. 
This is how I learned it, hope it helps.
 
        
        
        
In New Mexico is the prepositional phrase
        
                    
             
        
        
        
I think that there are three phrases which create comic tone:
dangling from his arm
someone who grew desperate
to fold up a bush
        
                    
             
        
        
        
A and F..though E also could have a misplaced modifier
