Question

How many decimeters make one metre?

Answer 1

Hint: Let us first go through the metric system and its different components and also the prefixes and their relations. Then we can find the relation between decameter and metre to solve the problem.

Complete step-by-step solution:
The metric system is a system of measurement that uses the meter, litre and gram as base units of length (distance), capacity (volume), and weight (mass) respectively. To measure smaller or larger quantities, we use units derived from the metric units.
Metre is a unit of length. We use prefixes to denote and find relations between smaller or larger quantities. The most common ones are Kilo, Hecto, Deca, Deci, Centi, Milli. We also have only a unit meter in between Deca and Deci.
They are related to the multiplication of 10.
Therefore, Decameter is just before the metre which gives 10 metres is equal to 1 Decameter.
Using unitary system, we get $\dfrac{1}{10}=0.1$ decameters make one metre.

Note: The decameter and metre are units of measurement for length in both the US customary units and the metric systems of measurement. This unit is used in the normal or common measurement units. It can also be changed to other common measurement units using the relation in the metric system.
