It is 400.
To round off 449 to the nearest 100, we look at the digit in the tens place, which is 4. Since 4 is less than 5, we keep the hundreds place digit the same and change all digits to the right to zero. Therefore, rounding 449 to the nearest 100 gives us 400.
As the first digit after the decimal point is a 5, we round up to give 23 as the answer.
Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the second number. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.
It is 450.
8.7
To round 449 to the nearest ten, you look at the digit in the tens place, which is 4. Since this digit is less than 5, you keep the tens digit the same and change all digits to the right of the tens place to zero. Therefore, rounding 449 to the nearest ten results in 450.
To round off 449 to the nearest 100, we look at the digit in the tens place, which is 4. Since 4 is less than 5, we keep the hundreds place digit the same and change all digits to the right to zero. Therefore, rounding 449 to the nearest 100 gives us 400.
0.8To round to 1 decimal place we look at the second digit after the decimal point and ask if it is equal to or greater than 5. If it is we round the first digit up (add 1 to it). If not we round down (the first digit remains the same).Here the second digit is "6" and so we round the first digit up to "8".
The hundreds, on either side of 449 are 400 and 500. 449 is 49 away from 400, and 51 away from 500. So the nearest hundred is 400.
you should round it to the nearest tenth and box the first number
To round a four-digit number to the nearest ten thousand, first identify the ten thousand place, which is the first digit on the left. If the digit in the thousand place (the second digit) is 5 or greater, round up by adding 10,000 to the ten thousand digit. If it's less than 5, keep the ten thousand digit the same and round down to the nearest ten thousand, effectively changing the number to 0.
To express 124.683 with one significant digit, we round it to the nearest ten. The first significant digit is '1' in the hundreds place, so we round 124.683 to 100.
It is: 450
If first digit of a number is 0-4, round down. If it is 5-9, round up.
You keep the first digit, replace the remaining digits with zero, and check whether you need to round the first digit up or not.
To round a number to the nearest thousand, first identify the hundreds digit (the third digit from the right). If this digit is 5 or greater, round up by adding 1 to the thousands digit and changing the digits to the right of it to zero. If the hundreds digit is less than 5, simply keep the thousands digit the same and change all digits to the right to zero.
When the last digit of a significant digit is 5 and we need to round it, we follow a rule called "round half up". This means that we round the digit up to the nearest number if the digit before it is odd, and round down if it's even. For example, 2.5 would round up to 3, while 3.5 would also round up to 4.
