Try 0.025 x 0.003 / 0.0005

$$0.025 \times 0.003$$

To multiply these decimals, we can multiply $25 \times 3 = 75$.
Then, count the total number of decimal places. 0.025 has 3 decimal places and 0.003 has 3 decimal places, for a total of $3+3=6$ decimal places.
So, the product is 0.000075.

We need to calculate $\frac{0.000075}{0.0005}$.
To simplify the division, we can multiply both the numerator and the denominator by 10,000 to make the denominator a whole number.

$$\frac{0.000075 \times 10000}{0.0005 \times 10000} = \frac{0.75}{5}$$

$$\frac{0.75}{5} = 0.15$$

The final answer is $\text{0.15}$.
