So the question is asking us to round 8188 to the nearest hundred.
If we take place value unto account, we have to look at the number in the hundreds column - in this case it says one hundred
Next we look to the column on the right of the 1 hundred - it is eighty
Because 8 > 5, we round up
Thus, the number we originally looked at should be increased by 1 and any digits to the right of it are turned into 0
As a result, the answer is 8200
hope it helped :)
