Answer:
1.804
Explanation:
In order for you to round off you need to know the place values of the numbers:
1- unit, 0- tenth, 8- hundredth, 3- thousandth, 6- ten thousandth
So you will focus on 6 and 3.
So because 6 which falls under the ten thousandth is bigger than 5 you write a 0 under it and add 1 to 3 making it 4.
Under the other numbers you do not change anything.
The answer becomes 1.804.
The 0 is just a place holder so it isn't neccessary to include it.
