No!If numerator and denominator have the same signs the fraction is positive.If numerator and denominator have opposite signs the fraction is negative.

-> Keep the same numerator.-> Multiply the denominator by the whole number, and make that the new denominator.-> Keep the negative sign before the fraction.You have the answer.

yes

Yes.

The fraction becomes less negative. It remains a negative fraction but moves nearer to 0.

If the numerator is negative and the denominator is positive then the fraction will be negative. If the numerator is negative and the denominator is negative too then the fraction will be positive.

just have the fraction be negative(do this by putting the negative symbol on the denominator, numerator or before the fraction).

The fraction becomes less negative. It remains a negative fraction but moves nearer to 0.

You can have negative exponents anywhere. When they are in the denominator, they are equivalent to positive exponents in the numerator of a fraction.

Example: (4x)-2 The answer to this would be 1/ 16x2. Multiply it out as if the negative exponent was not there ((4x)2), then that will be the denominator of the fraction. The numerator is one.

There is no simple answer to the question.If only the numerator is negative then the fraction is a negative fraction which may be proper or improper. If the numerator and the denominator have the same sign then the fraction is positive. It is an improper fraction if they are both negative and a proper fraction if they are both positive.

Multiply the numbers ignoring the signs and then add a negative sign.

The simplification will be positive. In other words, the numerator and the denominator will NOT stay negative.
