You identify the tenths digit 3.5 which is 5
5 is close to 10 so you round it to 4
4.9 = 9 is the tenths digit and you round it to 5
1.7 =7 is the tenths digit and you round it to 2
Hello!
As you can see, all of these numbers just go down to the tenths, not the hundreds, so we cannot round.
Therefore, the numbers will remain the same.
I hope this helps!
