Question

What is $200$ meters in kilometers?

Answer 1

Hint: Here this question belongs to the conversion topic, that is we have to convert the unit from one form to another. Here we have to convert the unit meters to the unit kilometers. In the question, we have to find what number of kilometers corresponds to $200$ meters.

Complete step by step answer:
The meters and kilometers are the units to measure the length of physical commodities or items. A meter is abbreviated as m and a kilometer is abbreviated as km. A kilometer is a metric unit of length and it is used for measuring comparatively larger stretches of length.The given question requires us to convert the unit of length. We have to convert $8$ meters into millimeters.

We know that each kilometer of length consists of $1000$ meters. So, $1\,km = 1000\,m$.Let the number of kilometers that correspond to $200$ meters be $x$. Then, to convert $200$ meters into kilometers, we follow the unitary method where we first find how many units of kilometers correspond to a single unit of meter and then multiply both sides of the equation by a suitable number so as to get the desired conversion of $200$ meters.So, we have, $1\,km = 1000\,m$

Dividing both sides by $1000$ and changing the sides of equation, we get,
$ \Rightarrow 1\,m = \dfrac{1}{{1000}}\,km$
Now, multiplying both the sides of equation by $200$, we get the conversion of $200$ meters as,
Hence, $200$ meters $ = $ $\dfrac{{200}}{{1000}}$ kilometers
So, cancelling the common factors in numerator and denominator, we get,
$ \dfrac{1}{5}\,$kilometers

Hence, $200$ meters is equal to $ \dfrac{1}{5}\,$kilometers.

Note: We have different units for solid quantity, liquid quantity, and gaseous quantity. Every quantity has a measurement unit from the low quantity to the high quantity.While converting the unit of a quantity from one form to another form we have a standard value. By multiplying or dividing we can convert the unit of the quantity.
