You divide the 100 times the numerator by the denominator. However, great care is required in interpreting the result. This is because 10 as a percentage of -20 has the same value as -10 as a percentage of 20 (both are -50%).

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.
This is the number of parts out of 100 the numerator of a fraction where the denominator is 100.?
It is the percentage.
If the numerator is negative and the denominator is positive is the number?
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 this15 divided by 3 is 515 divided by -3 would be -5so 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.
Is -15 rational or irrational?
Any integer, whether positive or negative, is a rational number. It can be expressed as a fraction with a negative numerator and a denominator of 1.
How do I work out fractions as percentages?
times the denominator by a number to get to a hundred then times the numerator by the same number. the final faction that you get, take the numerator and add a percentage sign and thats your percentage
How can a rational number be positive?
A rational number is simply a number that can be expressed as a fraction, with integer numerator and denominator. Such a number can be positive, negative, or zero.A rational number is simply a number that can be expressed as a fraction, with integer numerator and denominator.

How do you get the additive inverse for a negative denominator?
It is the same number without the negative sign.
How do you find the percentage of a number with a fraction?
Get the denominator to be 100.
This is the number of parts out of 100 the numerator of a fraction where the denominator is 100.?
It is the percentage.
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.
What values in the denominator must you be mindful of?
The denominator cannot be 0. If the denominator is a negative number, a fraction, a surd or a complex number (depends on your level), you are expected to rescale the fraction so that the denominator is a positive integer.
What is percentage mean?
The percentage of any number is the numerator when its value is expressed as a fraction with the denominator = 100.
How do you calculate a percentage change in excel if one number is negative?
To find the percentage change, you divide the change from initial to final by the absolute value of the initial value and then multiply by 100%. As an example: if the initial value is in cell A1 and the final value is in cell A2, the formula for percent change would be: =(A2-A1)/ABS(A1). You can EITHER multiply that value by 100 to get the percentage OR format the cell to display the number as a percentage. If the original number is negative and the final number is less (even more negative) - this makes the percentage change negative. If the original number is negative and the final number still negative but greater (closer to zero) then this would be an increase even though it would be less negative so the percent change would be positive. If the original number is negative and the final number zero or positive, this would still constitute an increase so the percentage change would be positive. If the initial number was positive and the final number negative, then this would be a pretty obvious decrease and the percentage change would be negative.
How do you make a decimal into a negative exponent?
You look at the denominator first. Then you try to find out what exponents make the denominator. After doing that, you add a negative symbol to the smaller number on the exponent.

What is the numerator of the fraction equivalent to that has a denominator of 60?
It can be any whole number. You really can't calculate the numerator based on the denominator.
