((1)/2z^2)) , ((2)/(3z^5))
a. 3z^3/6z^5 , 2/6z^5

c. none of these

The answer is b:
multiply the first expression by 3z^3/3z^3 and multiply the second by 2/2
(3z^3(1))/(3z^3(2z^2)), 2(2)/2(3z^5)
the result is:
3z^3/6z^5, 4/6z^5

Make the denominator same, that is make it 6z^5...
so mulitply the numerator and denominator of 1 / 2z^2 by 3z^3
which will give you,
3z^3 / 6z^5
similar for the second term, multiplying the numerator and denominator by 2, which will give,
4 / 6z^5
so the answer to your question is (b)
hope this helps!! :-)
