2.6 1.8 4.2 3.3 how do i estimate these decimals

Hello!

If the digit just to the right of it is less than 5, drop the digit to the left one. If the digit is greater than 5, you round it to the next decimal. So, the answers are:

2.6 rounded = 3 because 6 is greater than 5.

1.8 rounded = 2 because 8 is greater than 5.

4.2 rounded = 4 because 2 is less than 5.

3.3 rounded = 3 because 3 is less than 5.
