You could find common denominators a few times and multiply by reciprocals, but here we look at a shortcut for "clearing" the denominators: multiply top and bottom by the least common denominator of all fractions. This is mathematically valid because you're really just multiplying by a clever form of one, but the fractions will turn into integers.
