Question

How many meters is $120cm$ ?

Answer 1

Hint: Here in this question we have been asked to convert the given quantity in centimeters units $120cm$ to meters unit of length. From the basic concepts we know that one meter is equal to hundred centimeters in length.

Complete step-by-step solution:
Now considering from the question we have been asked to convert the given quantity in centimeters units $120cm$ to meters unit of length.
From the basic concepts we know that one meter is equal to hundred centimeters in length.
Now by using this statement we can mathematically write this as $1m=100cm$ .
Hence, by using the concept of proportions for converting a quantity in centimeters to meters we need to divide it by hundred. By doing this basic arithmetic simplification we will have $120cm=\dfrac{120}{100}m$ .
Therefore we can conclude that $120cm$ can be given as $1.2m$.

Note: During the process of answering questions we should be sure with the concepts that we are going to apply and the calculations that we are going to perform in between. This is a very simple and easy question and can be answered accurately in a short span of time. Very few mistakes are possible in this type of question. If someone had unintentionally made a calculation mistake during the simplification process and written it as $120cm=\dfrac{120}{100}m\Rightarrow 12.0m$ then they will end up having a wrong conclusion. So we should be careful while performing calculations.
