Answer:52.87
Which if you round it you would get 52.9
Step-by-step explanation: When you first do all the work you get 52.87,but some teachers like kids to round it like my teacher likes me to round if possible since you have 52.87 you look at the #7 when you round 7 is bigger than five so then you would make the 8 a 9 so then you would get 52.9.
Did not really know how to explain so I hope this helps
