Algebra I
Today we discussedWe are getting ready to wrap up our discussion of rational numbers. Today we applied all of the concepts we've learned so far to solving rational equations. All the rules for fractions and order of operations apply here. Keep in mind the degree of the equation will dictate how many solutions there are. One way to handle these problems is to multiply the entire equation by the least common denominator (AKA LCM).

Today we discussedAs an expansion of multiplying decimals and fractions, we discussed the circumference of circles. First we defined what a circle is, what the radius represents, and what the diameter is. We also used the formulas to find circumference when given either the radius or diameter.
