Whenever I reduce fractions I try to half them first, and keep halfing them until it can't be reduced anymore. So here we go:$$-\frac{ 30 }{ 54 }$$ divide by two on top and bottom$$-\frac{ 15 }{ 27 }$$ Now we can't half them anymore, so I'm going to divide the numerator and denominator by 3, because they can still be reduced further$$-\frac{ 5 }{ 9 }$$ This can't be reduced any further. So D is the correct answer.
