### Rounding turn off numbers We have currently learnt rounding off the numbers to the nearest tens, hundreds, etc. Permit us testimonial them. Let us consider a number, say 12 top top a number line. That lies in between 10 and also 20. We observe the the gap between 10 and also 12 is much less than the gap in between 12 and 20, i.e., 12 is nearer to 10 보다 20. So, us round off 12 come 10, that is, to the nearest ten.

You are watching: Round 345 to the nearest ten Similarly, if us take a number speak 16, then it is nearer to 20 as contrasted to 10. So, we will round turn off 16 come the nearest ten together 20. But if number 15 is considered, i m sorry is at equal distance from both 10 and also 20, the is also rounded turn off to 20. Similarly,

In 46, the digit in the ones ar is 6. Hence, 46 rounded turn off to the nearest ten is 50.In 251, the number in the ones location is 1. Hence, 251 rounded off to the nearest ten is 250.In 345, the digit in the tens location is 4. Hence, 345 rounded off to the nearest hundreds is 300.In 9157, the digit in the tens place is 5. Hence, 9157 rounded turn off to the nearest hundreds is 9200.In 5473, the digit at the hundreds ar is 4. Hence, 5473 rounded off to the nearest thousands is 5000.  ### Rounding turn off a number to the nearest ten thousand

Consider the digit in thousands location of the given number.If it is much less than 5, change the digits in thousands, hundreds, tens, and ones by 0, keeping the digits in other areas as castle are.If it is 5 or much more than 5, change the digits in thousands, hundreds, tens, and also ones by 0 and also increase the number in ten thousands through 1.
