To round the number 87671.5613658 to the nearest thousand, or the place value that is four to the left of the decimal, which would be the 7 bolded below:
87671.5613658
Consider the number to the right of it, 6. If the number is below 5, then you would round down to 87000 and if the number is 5 and above, then you round up to 88000. Because 6 is 5 and above, you would round up to 88000 which would be your answer. :)
