A bathroom-type scale is calibrated in tenths of a kilogram from 1 to 200 kg and you can estimate to the nearest two-hundredths of a kilogram How many significant figures should you use?
If the scale is calibrated in tenths of a kilogram I do not see how you can estimate to the nearest two hundredths of a kilogram! The calibration allows you to measure mass (in kilograms) to 1 decimal place. For masses less than 10 kg, that mean 2 significant figures. For masses of 10 kg or more but less than 100 kg, you can give the information to 3 sf and for masses of 100 kg or more, 3 sf.
