Question

Subtract: 1/3 - 5/6? *
​

Answer 1

`-(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
