Q. Which measurement is more precise?Choices:(A) 77.89g(B) 9.1g
Identify Given Measurements: Identify the given measurements and compare their decimal places.The given measurements are 77.89g and 9.1g. We need to compare the number of decimal places to determine which measurement is more precise.77.89g has two decimal places, while 9.1g has only one decimal place.
Compare Decimal Places: Determine which measurement is more precise based on the number of decimal places. Since the number of decimal places indicates the level of precision, the measurement with more decimal places is considered more precise. Therefore, 77.89 g, with two decimal places, is more precise than 9.1 g, which has only one decimal place.
