we know that
To Round a number
a) Decide which is the last digit to keep
b) Leave it the same if the next digit is less than [tex]5[/tex] (this is called rounding down)
c) But increase it by [tex]1[/tex] if the next digit is [tex]5[/tex] or more (this is called rounding up)
In this problem we have
[tex]33.01[/tex]
We want to keep the digit [tex]0[/tex]
The next digit is [tex]1[/tex] which is less than [tex]5[/tex], so no change is needed to [tex]0[/tex]
therefore
the answer is
[tex]33.0[/tex]
