Question

ending (trailing) zeros are ______ significant.
always
sometimes
never

Explanation:

To determine the significance of trailing zeros, we analyze different cases:

• For a number like \( 100 \) (without a decimal), the trailing zeros may not be significant (they could just be placeholders).
• For a number like \( 100. \) (with a decimal) or \( 1.00 \), the trailing zeros are significant (they indicate precision).

So trailing zeros are sometimes significant.

Answer:

B. sometimes
