A fraction is really the numerator divided by the denominator. When you divide two negatives together you get a positive, so, you automatically change it to positive.

Q: Why should there never be a negative sign in both the numerator and denominator of a fraction?

If the numerator and denominator are the same, the fraction simplifies to 1. And you should be able to subtract 1!

You should reduce a fraction if the numerator and denominator have any common factor greater than one.

An improper fraction in a mixed number means that the integer part of the mixed number should be increased: the denominator goes into the numerator at least one more type.An improper fraction in a mixed number means that the integer part of the mixed number should be increased: the denominator goes into the numerator at least one more type.An improper fraction in a mixed number means that the integer part of the mixed number should be increased: the denominator goes into the numerator at least one more type.An improper fraction in a mixed number means that the integer part of the mixed number should be increased: the denominator goes into the numerator at least one more type.

multiply the numerator and the denominator by a number.* * * * *by the same, non-zero number.Multiply both the numerator and denominator by a number of your choice. If both numbers are divisible by the same number, you should divide.

A proper fraction is one in which the absolute value of the numerator (the top) is smaller than the absolute value of the denominator.A sloppy definition would be that the numerator is smaller than the denominator. By that definition, -3/2 should be a proper fraction because -3 is less than 2.

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

Not really. 43/2 should be written as 51/2.

ex.1 2/3 take the base number and multiple that by the denominator and add by the numerator andAwhatever you get for that is your new numerator but you denominator stays the same as the last one so for this example you should get 5/3.

In a fraction they must be in the same units. In a ratio they need not be.

The result (which should be simplified) is another fraction of some kind: * a proper (or vulgar fraction) with the numerator (top number) less than the denominator (bottom number); * an improper fraction with the numerator greater than the denominator which can be converted into a mixed number; or * an integer (whole number).
