Round 129.392 to the nearest ten,one,tenth,and hundredth. I need help plz

"If number after the n-th place is greater than 5, add 1 to the n-th value. If it is less than 5, leave the n-th place value as it is, and remove all the numbers present after the tenth's place."

Rounding to the nearest one

"While rounding off to the nearest one-

If that digit next to the ones place is equal to 5 or greater than 5, we add 1 to the ones place digit of the number and remove the decimal part of the number. However, when that next place digit is less than 5, we keep the digit at ones place as it is and remove the decimal part. "

Rounding to the nearest ten

"While rounding off to the nearest ten-

if the digit in the units place is between 0 – 4 i.e., < 5 then the unit digit is replaced by 0.

if the digit in the units place is 5 to 9 i.e., > or 5 but < 10, then the units place is replaced by ‘0’ and the tens place increased by 1."

Given number is: 129.392

1) Rounding number to ten:

Here, tens digit is 2 (129.392)

The digit in the unit place (i.e., the digit after tens place) is 9 (129.392) which is greater than 5. So, the units place is replaced by ‘0’, the tens place increased by 1 and remove the decimal part of the number.

So, after rounding 129.392 to the nearest ten = 130

2) Rounding number to one:

For given number the ones digit is 9 (129.392)

Since the digit after 9 is 3 (129.392) which is less than 5, we keep the digit at ones place i.e., 9 as it is and remove the decimal part.

So, after rounding 129.392 to the nearest one = 129

3) Rounding number to the nearest tenth:

For given number the tenths digit is 3 (129.392)

The next smallest place value is 9 (129.392) which is greater than 5. So, we add one to the tenth place digit.

So, after rounding 129.392 to the nearest tenth = 129.4

4) Rounding number to the nearest hundredth:

For given number the hundredth digit is 9 (129.392)

The next digit after hundredth digit is 2 (129.392) which is less than 5. So, we replace that number (2) by zero.

So, after rounding 129.392 to the nearest hundredth = 129.390 or 129.39

Hence after rounding 129.392 to the nearest -

ten = 130

one = 129

tenth = 129.4

hundredth = 129.39
