A brief informal reasoning of why any division can be changed to a multiplication by reciprocating the second number or fraction, i. e. the number going into the other number. Then an example of…


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…


This states the Multiplicative Propery of Inequality, then demonstates how it works with two examples.


Simplification of two fractions withing a larger fraction. Both fractions have only multiplied factors in both numerator and denominator.


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


Demonstrates simplifying fractionis within fractions.


Shows how to convert Ax + By = C to y = mx + b then what and why the slopes for parallell and perpendicular lintes are what they are.


A couple of examples that combine sign combinations for diviision and using Keep/Change/Flip to convert fractioinal division to multiplication.


Just a short application of the "keep, change, flip" technique.


Uses the keep, change, flip mnemonic to demonstrate how you change all divisions of fractions to a multiplication of related fractions.


Shows you how to flip numbers or fractions to get the reciprocal. Hope it is obvious that reciprocals multiplied equal one.
