Answer:
As the number of significant figures increases, the more certain the measurement. As precision of a measurement increases, so does the number of significant figures. ... Trailing zeros (the right most zeros) are significant when there is a decimal point in the number.

The relation of precision to the significant figures in a measured quantity is explained as follows:
- The number of significant figures in any measurement indicates the degree of precision of that measurement.
- The degree of precision is found out by the least count of the measuring instrument.
- For example, a length measured by a metre scale of least count 0.1 cm is 1.5 cm, then it has two significant figures, namely 1 and 5.
- Measured with a vernier callipers of least count 0.01 cm the same length is 1.53 cm and it then has three significant figures.
- Measured with a screw gauge of least count 0.001 cm the same length may be 1.536 cm which has four significant figures.
