Never.
Whole numbers are positive numbers and there are no fractions or decimals.
Fractions are not integers.
A negative number divided by a negative number is positive. Therefore, it's the same as if both fractions were positive.
An example of a positive number without fractions or decimals is the whole number 7.
Divide as you would divide positive fractions. That is, convert both fractions to positive, then do the division. After that, apply the rules for dividing positive and negative numbers. For example, if one of the fractions is positive and the other negative, the answer will be negative.
You divide the equivalent positive numbers. Then you add a negative sign to the result.
It is the same as dividing two positive mixed fractions except that at the end of it all, you put a negative sign in front.
I think that equivalent fractions are fractions that have the same answer, at he end.
It is a counting number.
There is no end to the numbers of maths and there are many classifications of numbers, like primes, fractions, even, odd, positive, negative and others.
Subtracting a negative fraction is the same as adding its positive equivalent.
Yes, because for any x and y that are positive fractions (y not equal to zero), x/y is also a positive fraction. Note that whole numbers are considered fractions with denominators of 1 -- otherwise it doesn't work.
