The measurement 77.09m has four significant figures.
There are two significant figures in the measurement 210 cm.
the measured quantity with the least number of significant figures. For example, if you multiply a quantity with 3 significant figures by a quantity with 2 significant figures, your result should have 2 significant figures.
The least count of a measuring instrument is the smallest value that can be measured with the instrument. It determines the precision of the measurement. Significant figures, on the other hand, are the digits in a number that carry meaning about the precision of the measurement. The number of significant figures in a measurement is related to the least count of the instrument used to make that measurement.
The number 0.0102030 has 6 significant figures. Each of the non-zero numerals (3 of those), the zeros between the non-zero numbers (2), and the zero on the end of the number if it is right of the decimal (1). The significant figures are in bold:0.0102030
There are three. The 4, the 5 and the zero in between. The two last zeros serve only to properly space the decimal point which, in this number, is implied.
To determine the precision for a measurement of 120 meters, you need to consider the context of the measurement. Precision refers to the degree of refinement in a measurement, often indicated by the number of significant figures. If the measurement is given as 120 with no decimal places, it typically has three significant figures, suggesting that the value is precise to the nearest meter. If it were expressed as 120.0 meters, it would have four significant figures, indicating greater precision.
There are 4 significant figures in this number.

3 of them.
The number of significant figures should be equal to the significant figures in the least precise measurement.
4 of them.
0.0136
No, when multiplying or dividing measurements, the answer should have the same number of significant figures as the measurement with the fewest significant figures. This rule ensures that the precision of the result reflects the least precise measurement used in the calculation. Therefore, the final answer should be rounded accordingly to maintain appropriate significant figures.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The number of significant figures in a quantity represents the precision of the measurement. It indicates which digits are reliable and meaningful, reflecting the certainty of the measurement process. For example, in the number 0.00456, there are three significant figures, showing that the measurement is precise to that level. Therefore, significant figures help convey the degree of confidence in reported values in scientific and technical contexts.
the measured quantity with the least number of significant figures. For example, if you multiply a quantity with 3 significant figures by a quantity with 2 significant figures, your result should have 2 significant figures.
