Question

how to round 32,020.20 to the nearest 10th

Answer 1

look at the number to the right of the 10th place that number is 0. 0 is smaller than 5 so the number stays the same

Answer 2

Since you're rounding to the nearest tenth, look at the hundredth's place to determine whether you round up or down. In this case, the hundredth's place is the 0 after the 2. 

32,020.20 is already rounded to the nearest tenth.
