Let the number of thirds be x.
(2/5) = x(1/3)
2/5 = x/3
x/3 = 2/5
x = 2/5 * 3
x = 6/5
x = 1.2
Two-fifths equals 1.2 thirds
        
             
        
        
        
Answer:
x= 14 
Step-by-step explanation:

x = 31 - 17 
x = 14

The first one is 9/16 you have to make 54 and 96 a fraction such as 54/96 then simplify 
the second one is 1/5 you have to make 4 and 20 a fraction like this 4/20 then simplify 
hope this helps!!
