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.
36.4 microseconds is just fine.

Expressed as a decimal, 10/20 is equal to 0.5.
20 hundredths = 0.20
It is: 1/20 = 0.05

23/20 as a decimal is 1.15
19/20 = 95/100 = .95.19 over 20 as a decimal is 0.95
17/20 written as a decimal is 0.85
Expressed as a decimal, 10/20 is equal to 0.5.
20/100 written as a decimal is 0.2 or 0.20
20 hundredths = 0.20
It is: 1/20 = 0.05
20/1000th = .020
three- twentieths as a decimal = 0.153/20= 3 ÷ 20= 0.15 in decimal
