When adding or subtracting measurements, the result should have the same number of decimal places as the measurement with the fewest decimal places. When multiplying or dividing measurements, the result should have the same number of significant figures as the measurement with the fewest significant figures.
When multiplying/dividing measurements the answers needs to have the same amound significant figures as the one with the LEAST amount
When performing addition and subtraction operations with measurements of different significant figures, the result should be rounded to the same number of decimal places as the measurement with the fewest significant figures.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
4 significant figures.
To determine the number of significant figures in a measurement, you need to consider all non-zero digits, any zeros between significant figures, and trailing zeros in a decimal number. However, without specific measurements provided, I can't give an exact count. If you provide the underlined measurements, I can help you identify the significant figures in each.
When adding or subtracting measurements, the number of significant figures in the result should match the measurement with the least number of decimal places.
