6 23x4 2 is the exact percentile

AccuratePercentiles, i.e. to two decimal places, according to "rounding", ?The exact percentile is:

"Accurate to the percentile" means "two decimal places after the decimal point". That is, two decimal places are the percentiles, e.g., 0 01.

The decency is the first decimal place, and the percentile is the second decimal place. For example, in this decimal place, 1 is the tenth place and 2 is the percentile.

How to find an approximate number.

Rounding.

Rounding is a form of precision.

The counting retention method is essentially the same as the other methods. However, the peculiarity is that rounding is used so that the difference between the reserved part and the actual value does not exceed the last order of magnitude.

1/2: If the probability of 0 9 occurs, the sum of the errors of this retention method is minimal for a large number of retained data.

That's why we use this method as the basic retention method.

Advance method: The advance method is to remove the excess part of the number, and add 1 to the last number of the reserved part. The resulting approximation is an excess approximation (i.e., greater than the exact value).

Tail removal method: The tail removal method is a common mathematical method of removing the decimal part of the number and taking the integer part, and the value is an approximate value (smaller than the exact value), which is often used in life. It is also called the tail removal principle.

This is the divisor is a two-digit decimal division, in the decimal division to do the decimal division first according to the number of digits of the divisor, the dividend and the divisor at the same time to expand the same multiple, and then according to the integer division calculation method calculation, in this problem, the dividend and the divisor at the same time expand by 100 times, and then columnar calculation, that is, accurate to the percentile is to retain two decimal places, in the calculation to divide to the quotient is three digits before using rounding to retain two decimal places (accurate to the percentile). The vertical calculation is as follows.

Hello, the exact percentile is kept to two decimal places, so the percentile result is.

<> hope it can help you, if it helps you, please give a like, like in the upper right corner, thank you. (・

If this result is to be accurate to the percentile, then it should be approximately.

The exact percentile is about yes.

Accurate to the hundredth place (two decimal places).

Summary. The number is accurate to the tenths.

Simple calculation. Simple calculation.

Accurate to the 100 sharp slip fraction to know the land position, that is, to read the number to the second decimal place.

Hello, the number is accurate to the hundred-sky destruction of the quantile Douhu Yu rent, which is reserved to two decimal places, so the accurate to the percentile result is.

Summary. Accurate to the percentile).

Okay. Okay, got it.

Thank you, teacher. Did you get it, pro.
