A - 4/13ths is a larger number 
B-  3/10ths is a ratoinal mumner
 
        
                    
             
        
        
        
Ok so
x - the smallest
The other 4 are : x+1, x+2, x+3, x+4
We know that sum is 120
So
x+x+1+x+2+x+3+x+4=120
Combine like terms 
5x+10=120
Subtract 10 on both sides 
5x=120-10
5x=110
Divide by 5 on both sides 
X=22
The third number is x+2 = 22+2=24
        
             
        
        
        
Answer:
 12
Step-by-step explanation:
to find area you do length times width. if we have one side we have to find what 120/10 is. that is 12. 10 x 12 is 120.
