Opposite number is the same number with the opposite sign:

So the opposite of [tex] \frac{1}{3} [/tex] is [tex]-\frac{1}{3} [/tex], since the original number is positive

opposite of [tex]- \frac{7}{12} [/tex] is [tex]\frac{7}{12} [/tex], since the original number is negative
the opposite of 1/3 is -1/3.
the opposite of -7/12 is 7/12
