Numerators and denominators are just numbers; I hope you're not asking us to factor every number. There are many different methods. I prefer to find the prime factorization; that leads to all the other factors. Some people like to use a factor tree to help visualize the prime factorization.

Why do you multiply numerators and denominators by the same number?
you have to multiply numerators and denominators because whatever you do to the bottom you have to do to the top
What is relationship between numerators and denominators of factors and numerators and denominators of product?
this is a tricky question but the relationship between the numerators of the product is that they both fractions - and for the next question is that in some fraction their is aways going to have the same denominator that never changes or DONT CHANGE AT ALL !
What is the product of numerators and opposite denominators in a proportion called?
The answer is cross products.
How do you multiply fractions with variables?
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.
How do you subtract fractions with same denominators?
you subtract the numerators, and leeave the denomonators alone
What are denominators and numerators called?
They are called denominators and numerators!
How do you add if the numerators are the same and the denominators are different?
You have to make the fractions equivalent, which means you need to find the lowest common factor that goes into both the denominators.
Why do you multiply numerators and denominators by the same number?
you have to multiply numerators and denominators because whatever you do to the bottom you have to do to the top
If the denominators are different do you add them?
No. Convert them to like denominators and add the numerators.
What is relationship between numerators and denominators of factors and numerators and denominators of product?
this is a tricky question but the relationship between the numerators of the product is that they both fractions - and for the next question is that in some fraction their is aways going to have the same denominator that never changes or DONT CHANGE AT ALL !
What is the process of subtracting fractions?
If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.
How are all unit fractions alike and different?
Unit fractions all have the same numerators but the denominators can be different.
How do you multiply a fraction by a fraction by another fraction?
Multiply all the numerators together and then multiply all the denominators together
How are numerators and denominators alike?
numerators and denominators are both part of a fraction. the numerator is on top and the denominator is on the bottom. for example, in 2/3, 2 is the numerator and 3 is the denominator
How do you multiply fractions with uncommon denominators?
To multiply fractions all you do is multiply the numerators and the denominators separately eg: 4/7 x 6/11 = 24/77. The "commonality" of denominators has no relevance.
Can you add numbers with different numerators?
Yes, 'fractions' with different numerators can be added, but not with different denominators. In the case where you have different denominators, you must find the LCM (lowest common multiple).
What is the rule for multiplying fractions with like denamonators?
Multiply all numerators to get numerator of the product. Multiply all denominators to get denominator of the product. This is true whether the factors have like or unlike denominators.
