Question

Convert $0.001$ into percentage.

Answer 1

To convert decimal into percentage, we multiply it by $100$.

Step 1: Removing the decimal from $0.001$ and converting it to fraction.

We divide $0.001$ by $1000$ as it has values up to three places after the decimal.

Hence, $0.001=\frac{1}{1000}$

Step 2: To convert the fractional form into percentage, we multiply it by $100$.

$$\begin{gathered} \Rightarrow \frac{1}{1000}\times 100=\frac{1}{\cancel{1000}10}\times \cancel{100}1 \\ \Rightarrow \frac{1}{10}\%=0.1\% \end{gathered}$$

Hence, $0.001=0.1\%$
