fractions
When adding and subtracting fractions, we must have common denominators. This is the same as finding common multiples. Now we are going to merge 1) finding equivalent fractions and 2) find a common denominator.
Fractions which have the same value, even though they may look different.
Example 1/2 and 2/4 are equivalent, because they are both "half", the amount of pieces changes.
12 is the least common multiple, are there any others?
