As 800 is a whole number (as shown in the question) then: 800.00
800 in decimal form = 800.0
800,000.00
Expressed as a decimal, 800/1000 is equal to 0.8.
800/1000 = 0.800
It is already written in decimal form.
800 in decimal form = 800.0
800% = 80,000

1000 1000s is 1,000,000 There is no need for a decimal point.
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 decimal representation of 800 is 800, exactly as in the question. However, if you msut have a decimal point you could write is as 800. but without any trailing zeros since they would imply a higher level of precision for which there is no justification.
800%= 8.0 in decimal
decimal part of 800 is 160 = 0.2160/800:= 1/5= 0.2 in decimal
