Inequalities, Ratios, Proportions and Averages

Inequality

An inequality is a way of defining the relative site or order of two objects. To show that an unknown value is greater than a number, you would represent it as such:

$x>5$

Likewise, for less than:

$x<10$

If you combined these together, you would have this:

$5<x<10$

Which represents that x is greater than 5, but less than 10.
