Perform the operation and reduce the answer fully. Make sure to express your answer as a simplified fraction: -9/4 divided by 9/2

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of a fraction is found by flipping the numerator and denominator.

So, the reciprocal of 9/2 is 2/9.

Now, we can multiply:

-9/4 * 2/9 = (-9 * 2) / (4 * 9) = -18 / 36

To simplify the fraction, we notice that both the numerator and denominator can be divided by 18:

-18 / 36 = (-18 ÷ 18) / (36 ÷ 18) = -1 / 2

Therefore, the answer is -1/2.
