$-1/12 - (-3/4) = 2/3$

Get a common denominator.

$12$ is the least common denominator, so multiply:

$-3/4 xx 3/3$ , which is the same as multiplying by $1$ .

You get $-9/12.$

Simplify:

$-1/12 - (-9/12)larr$ NOTE: multiplying 2 negatives = positive

$= -1/12 + 9/12$

(Add numerators now that there is a common denominator.)

$= 8/12$

Simplify.

Divide each by $4$ to get a final answer of $2/3.$

$-1/12 - (-3/4) = 2/3$
