One-step Wrap-up AND LCM

Here is the key to Thursday in-class assignment. As a whole we reviewed the writing of an equation, the steps to solving the equation, labeling the answer, and the steps to checking work. At this time, we're taking a bit of a break from this concept and return in a few weeks.

Our next focus for the upcoming weeks will be LCM (lowest common multiple), LCD (lowest common denominator), divisibility, and adding/subtracting fractions.
