Q. What is the greatest possible error for a measurement of 8 tons?____ tons
Determine Precision: Determine the precision for the measurement of 8 tons.Since 8 is a whole number without any decimal or fractional parts, it is precise to the ones place.Precision: 1 ton
Calculate Error: Calculate the greatest possible error based on the precision.The greatest possible error for a measurement is half of the unit of precision.Greatest possible error =2Precision=21 ton=0.5 tons
