Rounding and Estimating Numbers

To round 800,000 to the nearest hundred thousand, it remains 800,000, as it is already at that value. The largest number that would round to 800,000 is 849,999, while the smallest number that would round to 800,000 is 750,000.

The root word for "rounded" is "round." The term "rounded" is formed by adding the suffix "-ed" to the root "round," indicating a shape that is curved or circular.

Florida is not a numerical value, so it cannot be rounded to the nearest tenth. If you're referring to a specific numerical statistic or measurement related to Florida, please provide that value, and I can help with rounding it.

425.919 rounded to the nearest whole number is 426. Since the digit after the decimal point is 9, which is 5 or greater, we round up the whole number part from 425 to 426.

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.

To find the high and low estimates of 541 - 293, we can round the numbers for simplicity. Rounding 541 to 540 and 293 to 300 gives a high estimate of 540 - 300 = 240. For a low estimate, rounding 541 down to 540 and 293 down to 290 results in 540 - 290 = 250. Therefore, the high estimate is 240, and the low estimate is 250.

When rounding 1.99999 to the nearest thousandths place, you look at the digit in the thousandths position, which is 9. Since the next digit (the ten-thousandths place) is also 9, it indicates that you should round up. Therefore, 1.99999 rounded to the nearest thousandths place becomes 2.0.

When rounding the number 213 to one significant figure, you look at the first digit, which is 2. The next digit is 1, which is less than 5, so you do not round up. Thus, 213 rounded to one significant figure is 200.

To round 8.275 to the nearest tenths of an ounce, you look at the hundredths place, which is 7. Since 7 is 5 or greater, you round up the tenths place from 2 to 3. Therefore, 8.275 rounded to the nearest tenths of an ounce is 8.3 ounces.

A hundredth of a second of 27.34 is 0.01 multiplied by 27.34, which equals 0.2734. This means that 27.34 seconds can be expressed as 27.34 seconds plus an additional 0.2734 seconds when considering the hundredth of a second.

To estimate (90 \times 0.4), you can round (0.4) to a simpler value. Since (0.4) is close to (0.5), you can estimate (90 \times 0.5), which equals (45). Thus, the estimate for (90 \times 0.4) would be slightly less than (45), around (36). A quick calculation gives (90 \times 0.4 = 36), confirming the estimate.

To round a number to the nearest 50, first identify the two multiples of 50 that are closest to the number. If the number is halfway between two multiples (e.g., 25 or 75), round up to the higher multiple. For numbers below the halfway point, round down to the lower multiple. For example, 120 rounds to 100, while 130 rounds to 150.

The nearest thousand to 7,593,656 is 7,594,000. This is determined by rounding the last three digits, 656, up to the nearest thousand. Since 656 is greater than 500, we round up to 7,594,000.

Estimation is helpful when dividing multi-digit numbers because it allows for a quick assessment of the quotient, making the division process more manageable. By rounding the numbers to simpler values, one can approximate the answer, which can guide the actual division and help identify any potential errors. This technique also aids in checking the reasonableness of the final answer, ensuring it falls within a plausible range.

The nearest Accident and Emergency department to the postcode M17 1WD is likely to be at Manchester Royal Infirmary, located approximately 3 miles away. Alternatively, the Salford Royal Hospital also has an A&E department and is around the same distance. It’s advisable to check online or call ahead to confirm services and wait times.

The number of significant figures on a graduated cylinder depends on its design and the precision of the markings. Typically, the last digit in a measurement is estimated, which means the total significant figures include all the certain digits plus one estimated digit. For example, if a graduated cylinder is marked in milliliters and has marks every 1 mL, you might report a measurement like 25.4 mL, indicating three significant figures (2, 5, and the estimated 0.4). Always consult the specific cylinder's markings for the most accurate determination.

To round 589 to the nearest tenth of a mile, we look at the digit in the hundredths place, which is 0. Since it is less than 5, we round down. Therefore, 589 rounded to the nearest tenth of a mile is 589.0 miles.

Life on Earth has existed for approximately 3.5 billion years. Given that the Earth is about 4.5 billion years old, life has been present for around 78% of Earth's history. Rounding to the nearest whole number, life has existed on Earth for about 78% of the time.

The number 4.5 is the same when rounded to the nearest tenth and the nearest whole number. When rounding 4.5 to the nearest tenth, it remains 4.5, and when rounding to the nearest whole number, it rounds up to 5. Therefore, 4.5 is unique in this regard.

To round numbers, identify the place value you want to round to (like the nearest whole number, tenth, hundredth, etc.). Look at the digit immediately to the right of that place value: if it's 5 or higher, increase the targeted digit by one; if it's 4 or lower, keep it the same. Finally, replace all digits to the right of the targeted place value with zeros or remove them, depending on the level of rounding. For example, rounding 3.76 to the nearest whole number results in 4.

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 round 5.8 to the nearest one, you look at the digit in the tenths place, which is 8. Since 8 is 5 or greater, you round up the number in the ones place, which is 5, to 6. Therefore, 5.8 rounded to the nearest one is 6.

9495.36 rounded to the nearest whole number is 9495. Since the decimal part, 0.36, is less than 0.5, we round down.

To round 219.109 to the nearest tenth, look at the digit in the hundredths place, which is 0. If this digit is 5 or greater, you round up the tenths place; if it's less than 5, you keep the tenths place the same. In this case, the tenths place is 1 and the hundredths place is 0, so you keep the tenths place as is. Therefore, 219.109 rounded to the nearest tenth is 219.1.

When rounding a number, you look at the digit immediately to the right of the place you are rounding to. If that digit is 5 or greater, you round up by adding one to the digit in the rounding place. If it's less than 5, you leave the rounding place digit unchanged. All digits to the right of the rounding place become zero (if rounding to a whole number) or are dropped (if rounding to a decimal).
