Answer:
1/6
Step-by-step explanation:
It'd be slightly easier to do this computation if we were to write it as follows:
20,000 7 1
------------ * ------------- * ------
1 15,000 56
20,000/15000 reduces to 20/15, or 4/3, and 7/56 reduces to 1/8.
4 1
Thus, we have ------ * -------
3 8
which in turn reduces to 1/6.
