You look at the denominator first. Then you try to find out what exponents make the denominator. After doing that, you add a negative symbol to the smaller number on the exponent.

If the events are independent then you can multiply the individual probabilities. But if they are not, you have to use conditional probabilities.

Repeated trials.

You can find a missing denominator if you know something that the fraction is equal to. Then you can find the missing denominator through cross multiplication.

You divide the numerator by the denominator.

-- Find any common factor of the numerator and denominator, and divide numerator and denominator by it. -- Keep doing that until the numerator and denominator no longer have any common factor except ' 1 '. The fraction is then in its simplest form.

There is really no such thing as a "greatest common denominator". Once you find the least common denominator of a set of numbers, you can keep adding the LCD to itself over and over again. Each new number you get will be a common denominator of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest denominator.There is really no such thing as a "greatest common denominator".
