In order to multiply fractions with variables, factor all numerators and denominators completely. Use the rules for multiplying and dividing fractions, cancel any common factors, and leave your final answer in factored form.
It's likely that you mean "factors." The factors of 25 are 1, 5 and 25. If you really meant fractions, please resubmit your question.
If the fractions do not all have the same denominator, find a common multiple of the denominators (ideally the lowest common multiple) and convert the fractions to equivalent fractions with this denominator. Now with all the fractions with the same denominator, add together the numerators. Finally, reduce the fraction to simplest terms, converting any improper fraction to a mixed number.
If two fractions have a common denominator of 8, it means that both fractions have 8 as their denominator. The fractions could be any two numbers as their numerators, such as 3/8 and 5/8, or 1/8 and 7/8. As long as the denominator is 8 for both fractions, the numerators can vary.
The first step in finding the lowest common denominator of two fractions is to multiply the two denominators. Then you see if there are any smaller numbers that are divisible by both denominators.
