Question. 52

The place value of a digit at the hundredths place is \(\tfrac{1}{10}\) times the same digit at the tenths place.

Answer:

true

Detailed Answer with Explanation:

Why this is true (step by step):

  1. In decimals, each place to the right is \(\tfrac{1}{10}\) of the place to its left.

    Tenths place value: \(\tfrac{1}{10}\)

    Hundredths place value: \(\tfrac{1}{100}\)

  2. Let the digit be \(d\). If \(d\) is in the tenths place, its value is:

    \(d \times \tfrac{1}{10}\)

  3. If the same \(d\) is in the hundredths place, its value is:

    \(d \times \tfrac{1}{100}\)

  4. Compare the two values by making a ratio (hundredths ÷ tenths):

    \(\dfrac{d \times \tfrac{1}{100}}{d \times \tfrac{1}{10}}\)

    Cancel \(d\): \(\dfrac{\tfrac{1}{100}}{\tfrac{1}{10}}\)

    Compute: \(\tfrac{1}{100} \div \tfrac{1}{10} = \tfrac{1}{10}\)

  5. Example: take \(d=5\).

    Tenths: \(0.5 = 5 \times \tfrac{1}{10}\)

    Hundredths: \(0.05 = 5 \times \tfrac{1}{100}\)

    \(0.05\) is \(\tfrac{1}{10}\) of \(0.5\).

Conclusion: The hundredths value is \(\tfrac{1}{10}\) of the tenths value, so the statement is true.
