To solve the proportions in the equations provided, we will first clarify what they represent.

Given the ratio \( X : \frac{4}{3} = \frac{3}{2} : 0.25 \) as a proportion, we can cross-multiply to find the value of \( X \).

1. **Set up the equation**:
\[
X \cdot 0.25 = \frac{4}{3} \cdot \frac{3}{2}
\]

2. **Calculate the right side**:
\[
\frac{4}{3} \cdot \frac{3}{2} = \frac{4 \cdot 3}{3 \cdot 2} = \frac{12}{6} = 2
\]

3. **Substituting back into the equation**:
\[
X \cdot 0.25 = 2
\]

4. **Solving for \( X \)**:
\[
X = \frac{2}{0.25} = 2 \cdot 4 = 8
\]

Thus, the solution to the first proportion gives us \( X = 8 \).

Now, moving on to the second proportion \( \frac{4}{3} = \frac{3}{2} : 0.25 \) implies a ratio comparison, but it seems incomplete in its formatting. However, if we evaluate:

- **Cross-multiply** again if it's structured similarly:
\[
\frac{4}{3} \cdot 0.25 = \frac{3}{2}
\]

- **Calculate the left side**:
\[
\frac{4}{3} \cdot 0.25 = \frac{4 \cdot 0.25}{3} = \frac{1}{3}
\]

Clearly, \( \frac{1}{3} \neq \frac{3}{2} \). Thus, this part does not provide an equivalent proportion.

The important computation is \( X = 8 \) based on the first set of the equation.
