Is your equation written wrongly or something? because if i use the equation u are giving, I get -512 which is not of any of the above...
14/15=28/30
1/2=15/30
28/30-15/30=13/30
the answer is 13/30 because you need to find the LCD(least common denominator) in order to minus，the LCD of 15 and 2 is 30 so you get 28/30 minus 15/30 and you get 13/30
