This video shows one method to convert the fraction to a decimal is by converting the denominator of the fraction to powers of 10 like 10, 100, 1000, etc. Note that this method is applicable only for the fractions whose denominator can be multiplied with a number to get a power of 10. For denominators that cannot be written as a power of 10, for example, 2/3, it is always better to use the long division.
