$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:-

First look into length measurement table :-

• $\bold{\red{Kilometre}}$↷×10
• $\bold{\red{Hectometre}}$↷×10
• $\bold{\red{Decametre}}$↷×10
• $\bold{\red{metre}}$
• $\bold{\red{Decimetre}}$↺÷10
• $\bold{\red{Centimetre}}$↺÷10
• $\bold{\red{millimetre}}$↺÷10

45 cm into Decametre

we need to divide it by 1000

$45cm = \frac{45}{1000} = 0.045dm$

45 cm into m

we need to divide it by 100

$45cm = \frac{45}{100} = 0.45m$

45 cm into Hectometre

we need to divide it by 10000

$45cm = \frac{45}{10000} = 0.0045hm$

45 cm into kilometres

we need to divide it by 100000

$45cm = \frac{45}{100000} = 0.00045km$
