Only if the number has an integer part.
That is correct.
False. In the number 0.032, the zeros to the left of the decimal point are not considered significant digits. Significant digits include only the non-zero digits and any zeros that are between them or to the right of the last non-zero digit. In this case, the significant digits are 3 and 2.
When they are between two non-zero digits or if there are after the decimal point. For example, the 0 is not significant in 1340 but it is significant in 1304 or 1340.0
The number 85000 has two significant digits. The trailing zeros are not considered significant unless there is a decimal point indicated (e.g., 85000. has five significant digits). Therefore, without a decimal point, only the digits '8' and '5' are counted as significant.
In the number 50.000, there are five significant digits. The zeros to the right of the decimal point are considered significant because they are trailing zeros following a decimal point. Trailing zeros in this context are significant as they indicate precision to the hundredths place.
No. 0.0000123 has three significant digits.
True
That is correct.
False. In the number 0.032, the zeros to the left of the decimal point are not considered significant digits. Significant digits include only the non-zero digits and any zeros that are between them or to the right of the last non-zero digit. In this case, the significant digits are 3 and 2.

No, they are not.
Zero is considered a significant digit when it is to the left or the right of the decimal point. It is also a significant digit when it follows a non-zero digit or when it is between two digits.
In the number 50.000, there are five significant digits. The zeros to the right of the decimal point are considered significant because they are trailing zeros following a decimal point. Trailing zeros in this context are significant as they indicate precision to the hundredths place.
The number 30900 has three significant digits: 3, 0, and 9. The trailing zeros are not considered significant unless indicated by a decimal point (e.g., 30900. has five significant digits). Therefore, without a decimal point, the significant digits are limited to the non-zero digits and the leading zero.
There are 3 significant digits in 4.00 and 2 significant digits in 7.0. Zeros between non-zero digits or at the end of a number after a decimal point are considered significant.
No, a leading zero is NEVER a significant digit.
