Introduction

Rounding numbers is a fundamental concept in mathematics that involves approximating a number to a specific place value. It is an essential skill that is used in various mathematical operations, such as addition, subtraction, multiplication, and division. In this article, we will focus on rounding the number 34.6285 to the nearest hundredths.

What is Rounding Numbers?

Rounding numbers is the process of approximating a number to a specific place value. It involves looking at the digit to the right of the place value and deciding whether to round up or down. The rules for rounding numbers are as follows:

If the digit to the right of the place value is less than 5, the number is rounded down.
If the digit to the right of the place value is 5 or greater, the number is rounded up.

Rounding 34.6285 to the Nearest Hundredths

To round 34.6285 to the nearest hundredths, we need to look at the digit to the right of the hundredths place, which is the thousandths place. The digit in the thousandths place is 8, which is greater than 5. Therefore, we round up the hundredths place.

Rounding Up the Hundredths Place

When we round up the hundredths place, we add 1 to the digit in the hundredths place. In this case, the digit in the hundredths place is 2, so we add 1 to it, making it 3. The number 34.6285 rounded to the nearest hundredths is 34.63.

Understanding the Options

Now that we have rounded 34.6285 to the nearest hundredths, let's look at the options provided:

A. 34.628 B. 34.63 C. 34.62 D. 34.629

Analyzing the Options

Option A, 34.628, is incorrect because it does not round the number to the nearest hundredths. Option C, 34.62, is also incorrect because it rounds the number down instead of up. Option D, 34.629, is incorrect because it rounds the number to the nearest thousandths instead of the nearest hundredths.

Conclusion

Rounding numbers is an essential skill in mathematics that involves approximating a number to a specific place value. In this article, we focused on rounding the number 34.6285 to the nearest hundredths. We applied the rules for rounding numbers and determined that the correct answer is 34.63. Understanding the concept of rounding numbers is crucial for performing mathematical operations accurately.
