Trailing zeros after the decimal point do not change a decimal's value.

• A. Trailing zeros change the value
• B. Trailing zeros do not change the value
• C. Trailing zeros only apply after decimal point
• D. Trailing zeros are meaningless

Answer: (B)

Trailing zeros after the decimal point don't change the numeric value because they’re just placeholders that show extra decimal places, not more quantity. In decimal notation, each digit has a place value, and zeros merely fill those places without adding anything new. For example, 3.1, 3.10, and 3.100 all represent the same amount; the extra zeros convey precision but not a larger or smaller number. The same idea applies to whole numbers: 50 and 50.0 are the same value, though the latter might suggest more precision. So the measured quantity stays the same, even if we add trailing zeros.
