Round 80,531 to the nearest
thousand.
We could use a number line to help
us solve this problem. For us to be able to round 80,531
to the nearest thousand, we need to know what the two multiples of a thousand either
side of this number are. To help us, we can start by looking
at the thousands digit itself. In this number, it’s a zero. This tells us that our number comes
somewhere between 80,000 and 81,000. One of these numbers is going to be
our answer, but which one?
Before we continue, let’s mark the
halfway point on our number line. Halfway is 80,500. Now, to work out where our number
belongs on this number line and whether to round it up or down, we need to look at
the digit to the right of the thousands digit. The hundreds digit is a five. Our number is eighty thousand five
hundred and something. This means we could say it’s about
here on our number line, just past halfway. We can see we’re going to need to
round it up to the nearest thousand. 80,531 rounded to the nearest
thousand is 81,000.
