Rounding to the Nearest Hundred

Rounded numbers are easier to work with in your head. Rounded numbers are only approximate. You can not get an exact answer with rounded numbers. Sometimes an exact answer is non needed.

To round numbers to the nearest hundred, make the numbers that end in 1 through 49 into the next lower number that ends in 00. For example 424 rounded to the nearest hundred would be 400. Numbers that have the last two digits of 50 or more should be rounded up to the next even hundred. The number 988 rounded to the nearest hundred would be 1000.

四捨五入至最接近的百

四捨五入，數字更容易在你的頭上。四捨五入，數字只是近似值。全面的數字，你不能得到一個確切的答案。有時一個確切的答案是無需要的。

數字四捨五入至最接近的百，使這些數字在1到49的結尾到下一個較低的數字，在00年結束。例如424四捨五入至最接近的百位是400。有50個或更多的最後兩位數字的數字應四捨五入到下一個甚至上百。988四捨五入至最接近的百1000。

Rounding Numbers

1. Rounding makes numbers that are easier to work with in your head.
2. Rounded numbers are only approximate.
3. An exact answer generally can not be obtained using rounded numbers.
4. Use rounding to get a answer that is close but that does not have to be exact.

How to round numbers

1. Make the numbers that end in 1 through 4 into the next lower number that ends in 0. For example 74 rounded to the nearest ten would be 70.
2. Numbers that end in a digit of 5 or more should be rounded up to the next even ten. The number 88 rounded to the nearest ten would be 90.

舍入數字

1.       四捨五入的數字是更容易在你的頭上。

2.       四捨五入，數字只是近似值。

3.       一個確切的答案，一般不能得到全面的數字。

4.       使用四捨五入得到的答案是關閉的，但沒有準確的。

如何舍入數字

1.       到下一個較低的數量，在0結束，使數字結尾的在1至4。例如，74四捨五入至最接近的十為70。

2.       為此，應在5個或更多的數字四捨五入到下一個偶數10的數字。四捨五入到最接近的十位的數目88​​將90。
