Rounding and Estimating Numbers

To the nearest thousandth, 1325

To the nearest thousand, 1000

A compatible number estimation is a technique used to simplify calculations by rounding numbers to values that are easier to work with, often whole numbers or numbers that are easy to divide. This approach makes mental math more manageable and helps provide a quick approximation of the actual answer. For example, when estimating the sum of 48 and 27, one might round 48 to 50 and 27 to 30, making it easier to compute a rough estimate of 80.

Price tags often end in .99 or .999 because this pricing strategy, known as psychological pricing, is designed to make products appear cheaper than they actually are. Consumers tend to perceive prices just below a round number as significantly lower, influencing their purchasing decisions. For example, $19.99 feels more appealing than $20.00, even though the difference is minimal. This tactic has been widely used in retail to boost sales and enhance consumer perception of value.

When rounding to a specific place, take a look at the digit immediately to the right of the target, in this case, the tenths place. If that digit is 4 or less, zero everything to the right of the target out. If that digit is 5 through 9, increase the target by one and zero everything to the right of it out. If the target is a 9, increasing it will turn it to zero and increase the digit to the left of the target by one.

126945 .

Inspect the hundred number, '9' in this case.

If the hundred number is '5' or greater , then you add '1' to the thousands number. ( 6 + 1 = 7)

Hence

127,000 is the answer.

NB if the hundreds number is 0 - 4 , then the thousands number remains unvhanges.

e.g. 126, 495 The hundred number is '4' in this case.

Hence to the nearest thousand it is 126,000

To the nearest ten, 650

To the nearest hundred, 600

To the nearest tenth, 649.0

To round 34279.38 to the nearest kilometer, you look at the digit in the tenths place, which is 3. Since it is less than 5, you round down. Therefore, 34279.38 rounded to the nearest kilometer is 34279 kilometers.

10

It is already to the nearest ten as 3490

0.9999 rounded to the nearest whole number is 1. This is because it is greater than 0.5, which means it rounds up to the next whole number.

To round .8 to the nearest tenth, you look at the digit in the hundredths place, which is 0. Since 0 is less than 5, you round down. Therefore, .8 rounded to the nearest tenth is .8.

It is already rounded to the nearest hundred thousand. You can't round a number to itself.

Round down to zero to the nearest hundred and 32.07 to the nearest hundredth.

what is 60,614 round to the nearest hundred

67 rounded to the nearest hundred is 100.

The Model 20ga 3 mod P fires 20-gauge shotgun shells. Specifically, it is designed to accommodate 3-inch (or 76mm) shells, which are commonly used in various shotgun applications. This size is ideal for hunting and sport shooting, providing a balance of power and manageable recoil.

To find the surface area of a pyramid, first calculate the area of the base, which depends on the shape (e.g., square, triangular). Then, determine the area of the triangular faces by using the formula for the area of a triangle (1/2 * base * height) for each triangular face. Add the area of the base to the sum of the areas of the triangular faces. Round the final result to the nearest whole number for the surface area.

380 ends with a zero, so it is already rounded to a ten, so it is 380.
