Answer:
[tex]n=0.63[/tex]
Step-by-step explanation:
The given statement can be expressed as an equation, as follows
[tex]10^{3} \times n = 630[/tex]
To solve it, we just need to isolate [tex]n[/tex], and solve
[tex]10^{3} \times n = 630\\n=\frac{630}{10^{3} }\\ n=\frac{630}{1000}\\ n=0.63[/tex]
Therefore, the solution for the given expression is
[tex]n=0.63[/tex]
