Answer: i think its the 3rd one
Step-by-step explanation:
 
        
             
        
        
        
U + 4/5 = 2 and 1/3
Subtract 4/5 from each side of the equation:
U = (2 and 1/3) - (4/5)
Now it's just problem in plain old adding and subtracting fractions,
just like the ones you've done many times before. 
First let's change (2 and 1/3) to a fraction:    2 and 1/3  =  7/3
So you have to find the value of  (7/3) - (4/5) .
In order to add or subtract fractions, they need to have a common denominator.
The least common multiple of 3 and 5 is 15, so that's a good choice.
7/3 = 35/15
4/5 = 12/15
Now the problem is:     (35/15) - (12/15).   
That's 23/15 . . . . . the same thing as <u>1 and 8/15</u> .   
That's the value of ' U '.  What an ugly number !
