2.6 1.8 4.2 3.3 how do i estimate these decimals

Masja [62]

Hello!

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

2.6 rounded = 3

1.8 rounded = 2

4.2 rounded = 4

3.3 rounded = 3
