To write 0.001 as a fraction, you need to consider the decimal place value. The decimal point is three places to the right of the decimal, so you can express 0.001 as 1/1000. This is because the decimal point separates the whole number from its fractional parts, with each place value representing a power of 10.
A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. So the required decimal representation is 100.
It is 20 microseconds, exactly as in the question. There is no requirement to express it as a fraction of some unspecified amount such as a second or a day or a millennium! A decimal number is simply a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point.
