Q: Which of the following is true about significant figures?
Solution: Trailing zeros in a decimal are significant.
Steps: 5
Step 1: Understand what significant figures are. They are the digits in a number that carry meaning contributing to its precision.
Step 2: Identify what trailing zeros are. Trailing zeros are the zeros that come after a decimal point and after a non-zero digit.
Step 3: Learn the rule about trailing zeros in decimal numbers. If a number has trailing zeros after a decimal point, those zeros are considered significant.
Step 4: Example: In the number 2.300, the trailing zeros (00) are significant because they indicate precision.
Step 5: Conclusion: Therefore, the statement 'Trailing zeros in a decimal are significant' is true.
