Question

when measuring an objects physical properties, how precise can ones estimate be?
a to the nearest half of a mark
b to the nearest tenth of a mark
c to the nearest whole mark
d to the nearest third of a mark

Explanation:

When measuring physical properties, the precision is often to the nearest tenth of a unit of measurement (mark in this context) as it provides a good - balance between accuracy and practicality. Smaller fractions like thirds are not as commonly used for general estimations, and halves are less precise than tenths. Whole marks are less precise compared to tenths.

Answer:

B. to the nearest tenth of a mark
