Question

Express in it simplest form 45cm :0.1m​

Answer 1

Answer:

$\frac{9}{2}$

or

$\frac{4.5}{1}$

Step-by-step explanation:

we have

$\frac{45}{0.1}\frac{cm}{m}$

we know that

$0.1=\frac{1}{10}$

substitute

$\frac{45}{0.1}\frac{cm}{m}=\frac{45}{(1/10)}=\frac{450}{1}\frac{cm}{m}$

Remember that

$1 \ m=100\ cm$

substitute

$\frac{450}{1}\frac{cm}{m}=\frac{450}{100}\frac{cm}{cm}$

Simplify

$\frac{450}{100}\frac{cm}{cm}=\frac{9}{2}$

or

$\frac{4.5}{1}$
