Question

Express 10,000 centimeters in kilometers.

• A. 0.1

Answer 1

The correct option is A 0.1
Centimeter is a unit of length.

Base 10 representation of Metric units is as follows:

Thousands	Hundreds	Tens	Ones	Tenths	Hundredths
Kilo	Hecto	Deca	Meter	Deci	Centi

As we move from right to left we divide by 10 by a certain number of times.

Kilometer is left of centimeter by 5 places.

To convert centimeters into kilometers, we need to divide the numbers of centimeters by 10 five times.

$\Rightarrow 10,000\text{Centimeters}=\frac{10,000}{10\times 10\times 10\times 10\times 10}\text{Kilometer}$

$\Rightarrow 10,000\text{Centimeters}=0.1\text{Kilometer}$
