Answer 2

$\textbf{Answer}$

$\textbf{Given value is 45 mm}$

We know that,
$\textbf{1 mm = 1/10 cm}$
=> 45 mm = 45/10 cm = 4.5 cm

We know that,
$\textbf{1 mm = 1000 m}$
=> 45 mm = 45/1000 m
=> 45 mm = 0.045 m

We know that,
$\textbf{1 mm = 1/10,00,000 km}$
=> 45 mm = 45/10,100,000
=> 45 mm = 0.000045 km

So the converted value of 45 mm-

$\textbf{4.5cm, 0.045m, 0.000045 km}$
