To determine which measurements represent the same level of precision, you need to compare the number of significant figures or decimal places in each measurement. Measurements with the same number of decimal places or significant figures indicate a similar level of precision. For example, 0.0050 and 0.050 both have two significant figures, thus representing the same level of precision.
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.
