A subtraction of fractionso where the denominators have no factors in common so we simpllly multiply the two together to create the LCD. Then both fractions are adjusted by multiplying each…


This shows how to determine a common denominator when the denominators share at least one factor. A numerical version is included for more understanding, and the rational expressions are added and…


This example shows how to factor each denominator and then determine which of these factors are needed to create the least common denominator (LCD). Then the fractions are expanded by multiplying…


An example that is easy to combine with subtraction, in this case, because the two fractions have common denominators. However, be aware that there may be a way to simplifying the answer further. …


This example shows how to add fractions with different denominators by adjusting one of the fractions so that they have a common denominator.


This demonstrates adding two rational expressions that have different terms individually in the numerator and a common denominator. When the fractions are added, it creates the possibility of adding…


This is a quick example of factoring the numerator and denominator of a combined fraction where all the factors are separated in order to find those that divide to one.


Shows how to use the given factors of two different denominators and find the LCD then adjust the fractions so they can be added


Evaluating a variable expression when you know specific number values for each varible.


A description of the process for dividing frations.


This is a second look at the multiplication of a fraction and a whole number, again reducing ahead of time before multiplying the fraction's tops and bottoms.


This demonstrates how to write a wholel number as a fraction, then how to reduce t he two fractionis before you multiply the numerators and denominators together to get the result.
