0,05•0,0005•5000000-1/3

Let's break down the calculation step by step.

1. Calculate \( 0.05 \times 0.0005 \): \[ 0.05 \times 0.0005 = 0.000025 \]

2. Now multiply the result by \( 5000000 \): \[ 0.000025 \times 5000000 = 125 \]

3. Finally, subtract \( \frac{1}{3} \) from \( 125 \): \[ 125 - \frac{1}{3} = 125 - 0.3333 \ldots \approx 124.6666 \ldots \]

So, \( 0.05 \times 0.0005 \times 5000000 - \frac{1}{3} \approx 124.6667 \) (rounded to four decimal places).
