Round 124531 to the nearest 10000. Round 124531 to the nearest 1000. Round 124531 to the nearest 100.

First, we have to round 124531 to the nearest 10000. The two digit in this number represents the ten thousands. Our number has two ten thousands, which is worth 20000. We have to decide if the number is closer to 120000 or 130000.

To help us round the number, we need to look to the digit to the right. Our number has 124000 and we can see it’s nearer to 120000. Now, we need to round 124531 to the nearest 1000. So we’re asking if it’s closer to 124000 or 125000. We’re rounding to the nearest 1000. If we looked to the digit to the right, which is the hundreds, this helps us to decide whether to round up or down. If this digit is five or more, we round up. So we round up to 125000.

And the final part of the question asks us to round our number to the nearest 100: 124500 or 124600. We can look to the digit to the right which is the tens column. Three is less than five. So we round down to 124500.

124531 rounded to the nearest 10000 is 120000, 124531 rounded to the nearest 1000 is 125000, and 124531 rounded to the nearest 100 is 124500.
