A billion is the unitary number multiplied by 10 to the power of 9.

A thousand is the unitary number multiplied by 10 to the power of 3.

A thousandth is the unitary number divided by 10 to the third power.
![(1)/(10^3)=0.001](https://img.qammunity.org/2023/formulas/mathematics/college/ekrx91brysag4la0cst51h0d337perkh4z.png)
If we have two billions, we just need to multiply one billion by two

Using the same argument for four hundred seventy-five thousand and one hundred fifty thousandths, we have
![\begin{gathered} 475*10^3=475,000 \\ (150)/(10^3)=0.150 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/juxd5xdz2cyybolfnx3wiq2g2c9tticuea.png)
Adding all those numbers together, we have
![2,000,000,000+475,000+0.150=2,000,475,000.150](https://img.qammunity.org/2023/formulas/mathematics/college/w4u82t6zpor6kizator6pa7dh8s1ecav92.png)
Our number is 2,000,475,000.150.
