Math Problem Statement

What digit is in a place with a value that is 100 times greater than the 5 in 7,326.305? Explain how you know.

Solution

In the number 7,326.305, the digit 5 is in the thousandths place. This means that its value is 5×110005 \times \frac{1}{1000}, or 5×1035 \times 10^{-3}.

We are asked to find the digit in a place with a value that is 100 times greater than this.

Steps to solve:

  1. Determine the place value of the 5:

    • The 5 is in the thousandths place, meaning its place value is 10310^{-3} (or 0.001).
  2. Multiply this place value by 100:

    • 100×103=101100 \times 10^{-3} = 10^{-1}, which is equivalent to the tenths place.
  3. Identify the digit in the tenths place:

    • The digit in the tenths place of 7,326.305 is 3.

Thus, the digit in the place with a value that is 100 times greater than the 5 is 3.

Conclusion:

The digit is 3, because it is in the tenths place, which has a place value 100 times greater than the thousandths place.
