This is a simple question on decimal conversion. Firstly, we need to understand time and decimal representation. Time can be expressed in hours, minutes, and seconds. There are 60 minutes in an hour, so when converting minutes to a decimal, we are finding what fraction of an hour those minutes represent. A decimal is a way to express a number that is not whole, using a decimal point (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
