What happens when you multiply a fraction by a fraction?
Just multiply straight through. Numerator times numerator and denominator times denominator. a/b * c/d = ac/bd ======
What happens when you add subtract multiply and divide fractions?
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).
What happens when you multiply a fraction by minus one?
The numerator changes sign.
What happens to the denominator when you add fractions?
You must find a common denominator. You figure out the smallest number that all of your denominators are divisible by. If you have to multiply the denominators by 2, you must multiply the numerators by 2, then add the numerators together, and write above the common denominator. If you have to multiply one denominator to equal the other denominator, then you must multiply the numerator above that denominator, and finally add up the numerators and place above the common denominator. Then reduce the answer to its smallest fraction.
What happens if you divide or multiply a ratio by different numbers?
If you mean multiplying numerator and denominator by different numbers, the result is then a different ratio. If you mean variously multiplying the numerator and denominator by the same number on different occasions, the result is unchanged.

If the numerator of the fraction is increased and the denominator doesn't change, then the value of the fraction increases.
What happens when decrease in numerator and increase in denominator?
The fraction gets smaller or increases, depending on whether the numerator and denominator are positive or negative.
What happens if your numerator is bigger then your denominator?
It is then an improper or 'top heavy' fraction
What happens to the value of a fraction when you double its denominator?
You have to double the numerator, but the value of the fraction remians the same but if you dont double the numerator then you dont have the same fraction
What happens when you add subtract multiply and divide fractions?
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).
What happens when you multiply a fraction by minus one?
The numerator changes sign.
When the numerator is the same as the denominator what happens?
The fraction reduces to 1 - UNLESS they are both zero, in which case the fraction is undefined.
What happens to the denominator when you add fractions?
You must find a common denominator. You figure out the smallest number that all of your denominators are divisible by. If you have to multiply the denominators by 2, you must multiply the numerators by 2, then add the numerators together, and write above the common denominator.
