Rounding and Estimating Numbers

The nearest tenth of a millimeter refers to rounding a measurement to one decimal place in millimeters. For example, if you have a measurement of 5.67 mm, rounding to the nearest tenth would result in 5.7 mm. Conversely, if the measurement were 5.64 mm, it would round down to 5.6 mm. This precision is often useful in fields such as engineering and manufacturing, where small variations can be significant.

The nearest multiple of 10 to 523 is 520. This is because 523 is closer to 520 than it is to 530, as it is only 3 units away from 520 compared to 7 units away from 530.

8.25 rounded to the nearest tenth of an ounce is 8.3. When rounding, you look at the digit in the hundredths place, which is 5 in this case, and since it is 5 or greater, you round up the tenths place from 2 to 3.

You would round 412 to 410 when rounding to the nearest ten, because the digit in the ones place (2) is less than 5. If rounding to the nearest hundred, you would round 412 to 400, as the digit in the tens place (1) is also less than 5.

5500 rounded to the nearest thousand is 6000. When rounding, you look at the hundreds place, which is 5 in this case. Since 5 or higher rounds up, 5500 becomes 6000.

To round the numeral 41 to the nearest ten, you look at the digit in the ones place, which is 1. Since 1 is less than 5, you round down. Therefore, 41 rounded to the nearest ten is 40.

The nearest ten thousand to 735286 is 740000. This is determined by looking at the thousands place, which is 5, and since it is 5 or greater, we round up the ten thousand digit from 3 to 4. Thus, 735286 rounds to 740000.

6.39 rounded to the nearest whole number is 6. When rounding, you look at the digit in the tenths place, which is 3 in this case. Since 3 is less than 5, you round down.

0.8 rounded to the nearest one is 1. Since it is closer to 1 than to 0, the value rounds up.

To round 5.71428571 to the nearest tenth, you look at the digit in the hundredths place, which is 1. Since 1 is less than 5, you round down. Therefore, 5.71428571 rounded to the nearest tenth is 5.7.

The nearest thousandth of 0.3333 is 0.333. Rounding to the nearest thousandth involves looking at the fourth decimal place, which is a 3 in this case. Since it is less than 5, we do not round up. Thus, the result remains 0.333.

To round 22.989 to a whole number, you look at the digit in the first decimal place, which is 9. Since 9 is greater than or equal to 5, you round up the whole number part, which is 22, to 23. Therefore, 22.989 rounded to the nearest whole number is 23.

The nearest ten thousand of 837,682 is 840,000. To round to the nearest ten thousand, you look at the thousands place, which is 7 in this case. Since 7 is greater than 5, you round up, resulting in 840,000.

The nearest hundredth of 2.2360679775 is 2.24. This is determined by rounding the number to two decimal places, where the third decimal place (6) indicates that we round up the second decimal place (3) to 4. Thus, 2.2360679775 rounded to the nearest hundredth is 2.24.

To round 56789 to the nearest thousand, you look at the hundreds digit, which is 7. Since 7 is 5 or greater, you round up. Therefore, 56789 rounded to the nearest thousand is 57000.

The nearest ten to 201 is 200, as it is the closest multiple of ten. The nearest hundred is also 200, since it is the closest multiple of one hundred.

.62 rounded to the nearest hundredth is .62. Since it is already expressed to two decimal places, there is no need for further rounding.

6.849 rounded to one significant figure is 7. This is because the first significant figure is the 6, and since the next digit (8) is 5 or greater, we round up. Therefore, 6.849 becomes 7.

To round 31817 to the nearest hundred, look at the tens digit, which is 1. Since 1 is less than 5, you round down. Therefore, 31817 rounded to the nearest hundred is 31800.

513.93 rounded to the nearest whole number is 514. When rounding, you look at the digit in the tenths place, which is 9 in this case. Since 9 is 5 or greater, you round up the whole number part from 513 to 514.

The nearest whole number for 16.79 is 17. When rounding, if the decimal is 0.5 or higher, you round up to the next whole number. Since 0.79 is greater than 0.5, you round 16.79 up to 17.

The expert judgment method of estimating task duration can be subjective and prone to bias, as it relies heavily on the opinions and experiences of a limited number of individuals. This can lead to over-optimism or pessimism, skewing the estimates. Additionally, if the experts lack experience with similar tasks or are influenced by groupthink, the accuracy of the estimates may suffer. Lastly, this method may not consider unforeseen variables, leading to potential underestimations of task complexity and duration.

To round 13.1355 to the nearest hundredth, you look at the third decimal place, which is 5. Since 5 is equal to or greater than 5, you round up the second decimal place from 3 to 4. Therefore, 13.1355 rounded to the nearest hundredth is 13.14.

To round the number 5419, identify the place value you want to round to. For example, if rounding to the nearest ten, look at the digit in the ones place (9). Since 9 is 5 or greater, you round up, resulting in 5420. If rounding to the nearest hundred, the digit in the tens place (1) is less than 5, so you round down to 5400.
