Rewrite and as fractions whose denominator is the LCD of and .
You can figure out the LCD for these fractions in one of two ways.
One: you can do the legwork, or two: you can look back up the page and
realize that we already tried this one. Keen observation will get you
far in this world.
We already know that the LCD for these two
fractions is 180. That means that, instead of and , we will
instead be working with the equivalent fractions of and .
Please show them to their cubicles.
