How many minutes are in $ 0.1 $ hour?

Hint: We need to convert the unit of $ 0.1 $ hour into minutes. We find the equivalent value of $ 0.1 $ hour in minutes. We use the relation between an hour and a minute where one hour is equal to 60 minutes. We multiply $ 0.1 $ with 60 to find the solution to the problem.

Complete step by step answer:
We need to convert the unit of $ 0.1 $ hour into minutes as we need to find the value of minutes in $ 0.1 $ hour.
We know the relation between an hour and a minute is that one hour is equal to 60 minutes.
We know the unitary system. The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
1 hour is equal to 60 minutes.
Hence, $ 0.1 $ hour will be equal to the multiplication of $ 0.1 $ with 60.
The multiplication value will be equal to $ 0.1\times 60=6 $.
Therefore, there are 6 minutes are in $ 0.1 $ hour.

Note:
In essence, this method is used to find the value of a unit from the value of a multiple, and hence the value of a multiple. We can also convert the decimal into its fraction form. We have $ 0.1 $ hour which is equal to $ 0.1=\dfrac{1}{10} $ hour. We can multiply $ \dfrac{1}{10} $ with 60 which gives a similar result of 6 minutes.
