Place value determines a digit’s value, and through which we can give names/write a particular number in words.
Digit’s Place | Ten Lakhs | Lakh’s | Ten Thousand’s | Thousand’s | Hundred’s | Ten’s | One’s |
Digit | 2 | 0 | 0 | 0 | 0 | 0 | 0 |
Place Value | \begin{equation} 2 \times 10^{6} \end{equation} | \begin{equation} 0 \times 10^{5} \end{equation} | \begin{equation} 0 \times 10^{4} \end{equation} | \begin{equation} 0 \times 10^{3} \end{equation} | \begin{equation} 0 \times 10^{2} \end{equation} | \begin{equation} 0 \times 10^{1} \end{equation} | \begin{equation} 0 \times 10^{0} \end{equation} 0100 |
In the expanded form, we can write 2,00,00,000 as
\begin{aligned}
&2 \times \text { Ten Lakhs }+0 \times \text { Lakhs }+0 \times \text { Ten thousand }+0 \times \text { Thousand }+0 \times \text { Hundred }+0 \times \text { Ten }+0 \times \text { One } \\
&=2 \times 1000000+0 \times 100000+0 \times 10000+0 \times 1000+0 \times 100+0 \times 10+0 \times 1 \\
&=2000000 \\
&=\text { Twenty lakhs }
\end{aligned}
Putting commas in 2000000
Position of the first comma - after 3 digits from the right.
