ANSWER
28.6
Step-by-step explanation
We are given the number 28.572 to the nearest tenth.
First, we locate the number in the tenth place value.
That is the number 5.
Now, we pick the number after it.
If that number is greater than 4, we round up to add 1 to 5.
If that number is less than or equal to 4, we round down to add 0 to 5.
7 is the number after 5 and it is greater than 4.
So we round up.
The number then becomes:
28.6
