Answer:


-(1)/(2)

Explanation:

When adding or subtracting fractions, you need to make sure that the denominators are the same:


(numerator)/(denominator_(x)) -(numerator)/(denominator_(y))
(numerator)/(denominator_(z)) -(numerator)/(denominator_(z))

To do this, you need to find the LCM of the denominators, and multiply top and bottom by the factor:


(1)/(3) -(5)/(6)

The denominators are 3 and 6. The lowest common multiple is 6, so you only need to change the first fraction by multiplying by 2. Multiply the top and bottom:


(2*1)/(2*3) =(2)/(6)

Insert into the expression:


(2)/(6) -(5)/(6)

Now subtract the numerators. The denominators will not change:


2-5=-3\\\\(2)/(6)-(5)/(6)=-(3)/(6) =-(1)/(2)

:Done
