Understanding Place Value in Numbers

Place value is a fundamental concept in mathematics that helps us understand the value of each digit in a number. It is the value that a digit holds in a number based on its position. In the decimal system, each position in a number has a specific place value, which is determined by the power of 10. The place value of a digit increases as we move from left to right in a number.

Identifying the 6-digit in the Number 205.876

To determine the place value of the 6-digit in the number 205.876, we need to identify the digit and its position in the number. The number 205.876 has six digits: 2, 0, 5, 8, 7, and 6. The digit 6 is the 6-digit in the number.

Understanding the Decimal System

The decimal system is a base-10 number system, which means that each position in a number has a place value that is a power of 10. The place values in the decimal system are as follows:

Ones (1)
Tens (10)
Hundreds (100)
Thousands (1000)
Ten thousands (10,000)
Hundred thousands (100,000)
Millions (1,000,000)
Ten millions (10,000,000)
Hundred millions (100,000,000)
Billions (1,000,000,000)
And so on.

Determining the Place Value of the 6-digit

Since the number 205.876 is a decimal number, we need to consider the decimal point when determining the place value of the 6-digit. The decimal point separates the whole number part from the fractional part. The whole number part is 205, and the fractional part is 0.876.

The 6-digit is the last digit in the fractional part, which is 6. To determine the place value of the 6-digit, we need to consider the position of the decimal point. The decimal point is between the 5 and the 8. This means that the 6-digit is in the thousandths place.

Conclusion

The place value of the 6-digit in the number 205.876 is thousandths. This is because the 6-digit is the last digit in the fractional part, and the decimal point is between the 5 and the 8.

Answer

The correct answer is D. Thousandths.
