The number would have to be negative. It really is the same as a positive numerator and denominator, just put a negative if the denominator is negative. Its like this
15 divided by 3 is 5
15 divided by -3 would be -5
so it asks what if the numerator was negative how many times would 3 go into it and the answer is -5.
(+)/(-)=(-)
(-)/(+)=(-)
(+)/(+)=(+)
(-)/(-)=(-)
same applies to addition and subtration and multiplication.
hope this helps.

How do you estimate a percentage when the denominator is a negative number?
Work the problem the same as usual, but then prefix the answer with the appropriate sign. First perform the division--numerator divided by the denominator--without regard to the sign. The sign of your answer depends on the combination of the signs of the numerator, the denominator, and the fraction itself. * If there are an even number of minus signs, the answer is positive. * If there are an odd number of minus signs, the answer is negative. * If there are an no minus signs, the answer is positive.
How do you turn negative exponents into positive exponents?
Put the number with the exponent in the denominator of a fraction and take off the negative symbol. The numerator in that fraction should be 1. Example: 8-2 Converts to: 1 --- 82

How do you you reduce a fraction with a negative number as a numerator?
To reduce a fraction with a negative number as a numerator, you can first simplify the fraction by finding the greatest common divisor (GCD) of the numerator and denominator. Then, divide both the numerator and denominator by their GCD and the negative sign remains unchanged. This will result in a reduced fraction with a negative numerator.
A fraction with a negative numerator whose absolute value is greater than its positive denominator is a number less than negative one?
Yes.

How do you find the product or quotient using positive exponents when you have negative ones?
Change the number or variable with the exponent from the numerator to the denominator, or from the denominator to the numerator, and at the same time change the exponent from negative to positive. For example, 5-3 = 1/53, and 1/x-10 = x10.

Can a rational number be negative in the denominator?
Yes. It can also be negative in the numerator. Both positive and negative numbers (as well as zero) can be rational numbers. Both positive and negative numbers can be irrational numbers. Both positive and negative numbers (as well as zero) can be integers.
How do you reduce a fraction with a negative number as the numerator and denominator?
A negative number divided by another negative number (much like a negative number multiplied by another negative number) gives you a positive result. The two minus signs cancel each other out.
What are some ways to find out if a number is greater than one-half?
It is if: * the numerator is greater than half the denominator. * twice the numerator is greater than the denominator. * the denominator is less than half the numerator. * twice the denominator is less than the numerator. * the decimal equivalent is gretaer than 0.5. * if you subtract 1/2, the answer is positive. * if you subtract it from 1/2 the answer is negative. * the square of the number is between greater than 1/4. There are many more.
How do you divide negative mixed number?
The first stage in dividing by a negative mixed number would be to convert that number into a top-heavy or vulgar fraction. Once this has been done, you ignore the negative sign for the time being, and multiply the number by the denominator. After this, you divide by the numerator. Finally, you swap the sign of the number you started with. If you were dividing a negative number the answer is positive. If you were dividing a positive number the answer is negative.
How do you divide a negative fraction by a whole number?
-> 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.
