Explanation:

To convert into metre

given :678 decimetre

First look into length measurement table :-

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

from above table :

$\bold{\boxed{1\:metre=10\: Decimetre}}$

Now,To convert into metre

Decimetre is smaller unit than metre so to convert into metre we have to divide the length value by 10 because 1 m=10 decimetre.

=>If bigger length value say km to convert into smaller unit say 'm' then in this case we have to multiply by 1000.

Divide the 678 value by 10 to convert into metre

$\bold{678 \: decimetre = \frac{678}{10} = 67.8 \: metre}$
