Concept explainers
(a)
Interpretation:
The given measurement is to be divided and the answer is rounded off to the proper significant digit.
Concept introduction:
In the multiplication or division of measurements, the answer is found to be limited by the measurement value with the lowest number of significant digits. The final unit in division is the ratio of the units of each data.
