Answer:
[tex]\frac{9}{2}[/tex]
or
[tex]\frac{4.5}{1}[/tex]
Step-by-step explanation:
we have
[tex]\frac{45}{0.1}\frac{cm}{m}[/tex]
we know that
[tex]0.1=\frac{1}{10}[/tex]
substitute
[tex]\frac{45}{0.1}\frac{cm}{m}=\frac{45}{(1/10)}=\frac{450}{1}\frac{cm}{m}[/tex]
Remember that
[tex]1 \ m=100\ cm[/tex]
substitute
[tex]\frac{450}{1}\frac{cm}{m}=\frac{450}{100}\frac{cm}{cm}[/tex]
Simplify
[tex]\frac{450}{100}\frac{cm}{cm}=\frac{9}{2}[/tex]
or
[tex]\frac{4.5}{1}[/tex]
