To solve the given expression, we can simplify it step by step.

1. Simplify the numerator:
10x * 0.12 * 25y = 3x * 25y = 75xy.

2. Simplify the denominator:
2z * 0.30x * 20y = 12xz * 20y = 240xyz.

3. Put the simplified numerator and denominator together:
(75xy) / (240xyz).

Now, we need to see if any terms can be canceled out or simplified further. In this case, we can see that both "y" terms can be canceled out from the numerator and the denominator, leaving us with:

75x / 240xz.

This is the simplified form of the expression (10x.12.25y / 2z.30x.20y).
