This example shows how to add fractions with different denominators by adjusting one of the fractions so that they have a common denominator.
|
|
|
Each denominator is factored and then any common factor is used only once and all other unique factors complete the LCD

|
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 demonstrates how to convert negative exponents in a complex fraction to the reciprocal positive exponents and then use the LCD of all fractions to simplify.
