Negative Fractions. Negative fractions are dealt with in the same way as whole negative numbers, and can also be calculated on a number line. For example, take the following problem and solution: This would follow the normal rule for adding positive numbers to negative numbers—start at the negative number, and count forwards (add).

If both are positive, it's positive. If both are negative, it's positive. Let's do one more example. Let's take 5-- I'm using the number 5 a lot. So let's do 3/2, just to show that this would work with improper fractions. 3/2 times negative 7/10. I'm arbitrarily picking colors. And so our numerator is going to be 3 times negative 7. 3 times ...


The process of adding and subtracting negative fractions can be straightforward, if you keep in mind two things. A negative fraction added to another negative fraction will result in a negative fraction as result. A negative fraction subtracted from another is the same thing as adding the positive complement of that fraction.


When you multiply a fraction by another fraction or a fraction by a whole number, the rules of fractions dictate the form of the answer. If at least one of the values is negative, you also use the rules for positive and negative signs to determine if the result is positive or negative.


The fraction is undefined. What about ? It's undefined, too, but for a slightly different reason. If you multiply the 0 in the denominator by any number at all you get the 0 in the numerator. It seems that can equal any number. As a result we say is indeterminate, which is a special kind of undefined expression. B. Negative Fractions. 1. is the ...

When you are adding or subtracting a negative fraction, you usually want to consider the numerator as negative. The method is just the same, except now you may need to add negative or positive numerators. 9 5 + (− 4 3) The LCM of 5 and 3 is 15 . To add the fractions with unlike denominators, rename the fractions with a common denominator.
