Hi there!
The correct answer for you is 270.88.
To round to the hundreth's place (.01), you need to take the number in the thousand's place (.001), and determine if the number needs to go up or down.
If the number in the thousand's place is greater than 4, then the number goes up.
360.727 --> This means that the hundreth's number goes up to 3.
If the number in the thousand's place is lesser than 5, then that number stays the same.
89.852 --> This means that the hundreth's number stays the same.
After you round, then just subtract:
360.73 - 89.85 = 270.88.
I hope this helps!
