Answer:
Accurate would be the answer I believe.
Step-by-step explanation:
A thermometer would be more accurate in tenths because it can get much closer to the actual value of the temperature that is being read. Let's say someone has a temperature of 98.7 a thermometer that is in the tenths would be accurate and say that the temperature is 98.7, but if it was in whole numbers it would have to round the temperature, which would be inaccurate.
Accuracy: description of how close a measurement is to an accepted or true value.
