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.
That is correct.
if between two other digits ex: 3009 or ending zeros when there is a decimal ex: 54.300
No, a leading zero is NEVER a significant digit.
There is nothing that zeros are always considered. Zeros in some positions are significant, in other position are not. There is no always.
Only if the number has an integer part.
No. 0.0000123 has three significant digits.
No, they are not.
True
That is correct.

No, a leading zero is NEVER a significant digit.
.625 is a terminating decimal. A decimal is considered terminating if it has a finite number of digits after the decimal point. In the case of .625, there are only three digits after the decimal point, making it a terminating decimal.
All digits between the first non-zero digit and the last non-zero digits are significant. Some would argue that trailing 0s are significant since they are an indication of the precision of the number.
A number with a finite number of decimal digits is always rational. (If the number of decimal digits is infinite, the number is rational only if there is a repeating pattern.)
There is nothing that zeros are always considered. Zeros in some positions are significant, in other position are not. There is no always.
Only if the number has an integer part.
False, Zeros are only significant digits when there is a primary number such as 1 before the as in 3200, then two zeros are counted but if zeros are before as in 0.032 than the only digits counted are 3 and 2.
