Count all the digits, from the first to the last non-zero digit. Include any zeros in between in the count. For example, 105 and 10500 both have three significant digits. Also include any zero after the last non-zero digit, only if it comes after a decimal point. Thus, 0.001050 has four significant digits, since you need to count the last zero.
You count the number of figures from left to right starting with the first number different from 0. Example: 205 has 3 significant figures 0.0000205 has 3 significant figures 0.000020500000 has 8 significant figures
There are two significant figures in 0.025.
That depends on how many significant figures you are talking about.If three significant figures then 700 is the largest that rounds to 700.If four significant figures are to be rounded to three significant figures then 700.4If five significant figures are to be rounded to three significant figures then 700.49If six significant figures are to be rounded to three significant figures then 700.499etc.
The significant figures in 0.000042500 are: 0.0000425. So, there are 8 significant figures.

When performing addition and subtraction operations with measurements of different significant figures, the result should be rounded to the same number of decimal places as the measurement with the fewest significant figures.
