Rounding and Estimating Numbers

The nearest thousand to 14,500 is 15,000. When rounding to the nearest thousand, you look at the hundreds digit, which in this case is 5. Since 5 or greater means you round up, 14,500 rounds up to 15,000.

To round 2.85 tons to the nearest hundredth, you look at the third decimal place. Since there are no digits beyond the hundredth place, 2.85 rounded to the nearest hundredth remains 2.85 tons.

To round 0.416 to the nearest tenth, you look at the digit in the hundredths place, which is 1. Since 1 is less than 5, you do not increase the tenths place digit (4). Therefore, 0.416 rounded to the nearest tenth is 0.4.

To round 25.254 to the tenths place, you look at the digit in the hundredths place, which is 5. Since 5 is equal to or greater than 5, you round up the tenths place digit (which is 2) by 1. Therefore, 25.254 rounded to the tenths place is 25.3.

18999 rounded to the nearest ten is 19000. Since the digit in the ones place is 9, which is 5 or greater, we round up the tens place from 9 to 0 and increase the hundreds place by 1. Thus, 18999 becomes 19000.

To round 14,892,391 to the nearest million, you look at the hundreds of thousands place, which is 892,391. Since this number is greater than 500,000, you round up. Therefore, 14,892,391 rounded to the nearest million is 15,000,000.

To round 1.28372 to the nearest thousandth, you look at the digit in the thousandths place, which is the third digit to the right of the decimal point (3 in this case). Next, check the digit immediately to its right (the fourth digit), which is 7. Since 7 is greater than 5, you round up the thousandths place digit from 3 to 4. Therefore, 1.28372 rounded to the nearest thousandth is 1.284.

To round 1604 to the nearest hundred, you look at the digit in the tens place, which is 0. Since 0 is less than 5, you round down, keeping the hundreds digit the same. Therefore, 1604 rounded to the nearest hundred is 1600.

To provide an appropriate cost estimating technique, I would need specific details about the situation in question. Generally, techniques like analogous estimating can be useful when there is historical data from similar projects, while parametric estimating is effective when project parameters can be quantified. For detailed and complex projects, bottom-up estimating may be more accurate, as it involves estimating costs for individual activities and summing them up. Please provide more details for a tailored recommendation.

Rounding involves adjusting a number to a specified degree of accuracy, typically to make calculations simpler, such as rounding 4.7 to 5. Estimating, on the other hand, involves making an approximate calculation or judgment about a quantity without exact precision, often using rounded numbers to quickly assess a situation. While rounding gives a precise value based on a rule, estimating provides a broader, more flexible approach to understand or analyze quantities.

In my job, I use rounding primarily to simplify numerical data for reporting and analysis. For instance, when presenting financial figures, rounding to the nearest whole number or two decimal places makes the information easier to digest. It also helps in estimating values when precise numbers are not necessary, ensuring clarity in communication among team members and stakeholders. This practice enhances accuracy in decision-making without overwhelming the audience with excessive detail.

To round 8.16 to the nearest ten dollars, you look at the value in the units place, which is 8. Since it's closer to 0 than to 10, you round down. Therefore, 8.16 rounded to the nearest ten dollars is 0.

To round the number 857836 to the nearest 10,000, we look at the digit in the 1,000s place, which is 7. Since 7 is greater than or equal to 5, we round up. Therefore, 857836 rounded to the nearest 10,000 is 860,000.

It is: 6.4

To round 379.94 to the nearest tenth, look at the digit in the hundredths place, which is 4. Since 4 is less than 5, you do not round up. Therefore, 379.94 rounded to the nearest tenth is 379.9.

61.35 rounded to the nearest tenth is 61.4. When rounding, you look at the hundredths place (which is 5 in this case). Since it's 5 or greater, you round up the tenths place from 3 to 4.

To round 83,277 to the nearest thousand, you look at the digit in the hundreds place, which is 2. Since 2 is less than 5, you round down. Therefore, 83,277 rounded to the nearest thousand is 83,000.

520

To round 4302 to the nearest 100, you look at the digit in the tens place, which is 0. Since 0 is less than 5, you round down. Therefore, 4302 rounded to the nearest 100 is 4300.

129.906

5.96 rounded to the nearest whole number is 6. When rounding, you look at the digit in the tenths place, which is 9. Since 9 is greater than 5, you round up the whole number from 5 to 6.

600

The nearest multiple of 10 to 24 is 20. To find the distance, subtract 20 from 24, which gives you 4. Therefore, 24 is 4 units away from the nearest 10.
