Reduce to lowest terms
4 is the numerator and 16/3 is the denominator. don't know how to write it out on here.

Step-by-step explanation:

If fraction is in denominator, find the reciprocal of it and multiply

3/4

Step-by-step explanation:

Let me assume you meant:

(4) / (16/3)

If that is it; we can further express it as:

= (4 * 3) / 16

= 12 / 16

(Divide through by 4)

= 3 / 4

I only hope that was the right expression.
