What is the difference? 5/3-1/2a. 4b. 7c. 7/6d. 7/0 = undefined

The answer is:  [C]:  " ⁷/₆ " .

  Note:

   (5/3) - (1/2) = ? ;

The LCD (lowest common denominator) of "2 and 3" is "6" ;

So we need to rewrite EACH fraction in the problem as a fraction with "6" in the denominator ;

 (5/3) = (?/6) ?  ;  (6÷3=2) ;  (5/3) = (5*2)/(3*2) = 10/6 ;

(1/2) = (?/6) ? ; (6÷2=3) ;  (1/2) = (1*3)/(2*3) = 3/6 ;

Rewrite the problem:   "    (5/3) - (1/2) " ;  as:

   10/6 - 3/6  ;

    10/6 - 3/6 = (10 - 3) / 6 = (7/6) = 1 ⅙ .

The answer is:  " ⁷/₆ " ;  or, write as:   " 1 ⅙ " ; which corresponds to: 

Answer choice:  [C]:  " ⁷/₆ " .
