How do you write 800 using decimal points?

Answer 1

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.

Answer 2

Oh honey, it's simple math. Just write 800.0. There you have it, 800 with a decimal point. Easy peasy lemon squeezy.
