To solve the expression \(\left(\frac{27}{125}\right)^{\frac{1}{3}} \times \frac{3}{9} \div \left(25\right)^{-\frac{1}{2}}\), let's break it down step by step.

### Step 1: Simplify \(\left(\frac{27}{125}\right)^{\frac{1}{3}}\)
The cube root of \(\frac{27}{125}\) is:
\[
\left(\frac{27}{125}\right)^{\frac{1}{3}} = \frac{\sqrt[3]{27}}{\sqrt[3]{125}} = \frac{3}{5}
\]

### Step 2: Simplify \(\frac{3}{9}\)
\[
\frac{3}{9} = \frac{1}{3}
\]

### Step 3: Simplify \(\left(25\right)^{-\frac{1}{2}}\)
\[
\left(25\right)^{-\frac{1}{2}} = \frac{1}{\sqrt{25}} = \frac{1}{5}
\]

### Step 4: Combine all the results
Now we substitute these back into the expression:
\[
\frac{3}{5} \times \frac{1}{3} \div \frac{1}{5}
\]

### Step 5: Simplify the multiplication and division
Multiplication:
\[
\frac{3}{5} \times \frac{1}{3} = \frac{3 \times 1}{5 \times 3} = \frac{1}{5}
\]
Division:
\[
\frac{1}{5} \div \frac{1}{5} = \frac{1}{5} \times \frac{5}{1} = 1
\]

The final result is:
\[
\boxed{1}
\]
