### What is the opposite of one-half?

That depends what you mean with "opposite". Two important math
concepts are:
a) The additive inverse. That's the same number, with a minus in
front of it (a number plus its additive inverse = 0).
b) The multiplicative inverse, also called the reciprocal. One
divide by the number. For a fraction, you can simply exchange
numerator and denominator to get the reciprocal. (A number times
its reciprocal = 1.)

### How do you divide a fraction?

multiply it by its reciprocal by flipping it around. For
example, if you had one half (1/2) divided by one third (1/3), you
would multiply one half by 3 (the reciprocal of 1/3) to get your
answer. This works for fractions with variables, too, but make sure
you factor first.
Multiply the first fraction by the reciprocal of the second
one,
3/4 divided by 4/5 = 3/4 x 5/4
