A The key to solving this kind of equation is multiplying through by the least common denominator to eliminate the fractions first, Then it is a matter of combining like terms on one side of the…


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…


A complex fraction is multiplied through on the top and the bottom by the common denominator of all smaller fractions, eliminating the denominators of those smaller fractions.


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 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…


A quick presentation of why we only add the numerators of fractions with common denominators, and then a quick example of adding two fractions with the same denominator.


A demonstration of how factoring is used to discover the minumum number of factors that need to be combined to find the smallest denominator that can be used as the LCD of the two given fractions.


This describes the process of solving for a particular variable in terms of other variables in an equation. There is a need to go further to combine like terms before it is complete.


Two quick demonstratoins of a rational expression containing radicals being ratioinalized by multiplication of a form of one to transform a radical in the denominantor to a whole number.


This demonstrates creating a multiplication in the numerator of a rational expression that will allow the expression to be reduced by dividing like factors to simply one


This video shows how to multiplly the top and bottom of a square root of a fraction to get the result of a rational number in the denominator.


Demonstrates using factoring skills to separate and identify all of the necessary factors that make the LCD (Least common denominator) that can be used as a multiplier through a rational equation to…


Shows how to find a common denominator to use as a multiplier for each term in a rational equation (an equation with fractions) to then eliminate the denotminators and the result will be a more…


Shows how to simplify a large fractions with fractioins embedded in it. The simplest way involves multiplying all small fractions by their least common denominator so the individual denominators…


An explanation of two single fractions divided with monomial denominators and how to simplify them


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