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 quick justification of dividing fractions by multiplying by the reciprocal of the second fraction in the division followed by an example that involves reducing the common factors in the numerator…
|
|
|
A short reminder of how to reduce first and then multiply two numerical fractions. Then we apply the same priciples to reducing like factors in an example with more than one variable and numerical…

A review of the sign rules for multiplication and three examples to demonstrate these.
|
|
|
This discusses what rationals and irratioinals are, then goes on to demonstrate how to eliminate any radical number in the denominator.
|
|
|
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.

|
A two step process is shown here. First, as always, look for a greatest common factor (GCF) and remove it from all terms. Then second, the resulting quadratic expresssion can then be factored into…

A second example of how to use multiplication or division to isolate a chosen variable in a formula.
|
