Answer:
3/20
Step-by-step explanation:
Your calculator can help with this. Put the numbers in place of the variables and do the arithmetic. The mixed number can be converted to an improper fraction. Factors of 3² can be removed from numerator and denominator because they cancel.
x·x·y·z = (1/3)·(1/3)·(3/5)·(2 1/4) = (1/3)(1/3)(3/5)(9/4)
= (1·1·3·9)/(3·3·5·4) = 3/20
