0.1020 is a number to 4 significant figures. The rule is that "Zeros must be kept to show the position of the decimal point or to indicate that zero is a significant figure." Then the leading zero before the decimal point is retained as this shows the position of the decimal point. The zero between 1 and 2 is a key part of the number. The final zero (after 2) is a significant figure otherwise the number would be written 0.102. Consequently, the 4 significant figures are "1020" but are presented as 0.1020 to ensure the true value of the number is accurately given.
It is in the hundreds' place so its value is 700.

Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value.
The number 12882 to one significant figure is 10000. When rounding to one significant figure, you focus on the highest place value, which is the first digit (1 in this case), while adjusting the other digits accordingly. Thus, 12882 rounded to one significant figure becomes 10000.
When expressing a number to one significant figure, you round it to the nearest power of 10. In this case, 150.932 to 1 significant figure would be 200. Since 150.932 is closer to 200 than to 100, the rounded value is 200.
It refers to the number of of some numerical value thet was obtained from an accepted level of accuracy
3. The first non zero number is the first significant figure. All numbers after this are significant. Trailing zeros after the decimal place have no value
The number 0.048 has two significant figures. The leading zeros (the zeros before the 4) are not counted as significant figures. Only the digits 4 and 8 are significant in this value.
The number 151.208, when expressed to two significant figures, is 150. This is because the first two significant figures are '1' and '5', and rounding the next digit (which is '1') leads to a decrease in the last significant figure. Therefore, the rounded value is 150.
The percent error in the measurement of density is calculated by taking the absolute difference between the measured value and the accepted value, dividing it by the accepted value, and then multiplying by 100. The result is rounded to the appropriate number of significant figures.
There are three significant figures in the number 8.09. The first two digits, 8 and 0, are considered significant because they are non-zero numbers. The third digit, 9, is also significant because it follows a non-zero number and is a measured value.
