Apr 10

We started with a warm-up to review when the inequality symbol needs to switch direction.

We saw that for any inequalities (or equations) that have fractions, one method to deal with them was to change every term to common denominators. Then all the denominators can be removed. We practiced writing expressions with common denominators.
