5-4 Multiplying and Dividing Fractions – We reviewed that subtracting integers involves making 2 changes to the expression. Then we learned that when you divide you also make 2 changes. You multiply by the reciprocal of the 2nd fraction or divisor. Next we learned that these 2 actions offset each other so that the value of the expression remains unchanged.

5-3 Adding and Subtracting Fractions – We learned to add and subtract fractions with unlike denominators by rewriting the fractions with a common denominator. Then we learned that using the least common denominator or LCD results in numerators having the least possible values so they are easier to add and usually the result is already in simplest form.

We went over the rules of exponents and learned when the rules apply and when they don’t. We understand now that the product and quotient rules only apply when we are working with the same base number. The exponent rules are essential to simplifying algebraic expressions and solving algebraic equations.
5-1 Comparing and Ordering Rational Numbers – We learned to find the least common multiple LCM of variable expressions and to compare fractions. Then we learned how to use the least common multiple as a common denominator.
