only if the positive fraction is "larger" than the negative one.
It can be a negative or positive fraction, a negative or positive integer, or zero.
You could multiply the fraction by -1.
If you mean negative numerator and negative denominator then the answer is Yes.
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.
Add a positive number - fraction or integer - to the given fraction.
-- Ignore the signs. -- Divide the first fraction by the second fraction, then decide whether the answer is positive or negative. -- If both numbers in a division have the same sign, then the quotient is positive. So the quotient is positive, and you're done.
The result in this case is positive.
if you mean like, (-10)/5, then yes, it is simply a negative fraction, which works just like negative numbers.
If you mean the difference in terms of numerical value, then it is the positive faction minus the negative faction, which is calculated as the positive fraction plus the absolute value* of the negative fraction - just like the difference between a positive and negative number. * The absolute value of a number is the value of the number ignoring any minus sign; eg abs(-4) = 4 = abs(4). If you mean the difference in terms of where they are on the number line, then the positive fraction is one side of zero (it is greater than zero) and the negative fraction is the other side of zero (it is less than zero).
in the fraction 9/10 the positive reciprocity is 9
