Left zero's are NOT significant: So it's one in 0.01
There is one significant figure in the number .001. Leading zeroes, which only serve to indicate the position of the decimal, are never significant.
there is one significant figure in 001 because 0's only count as significant figures when they are after a whole number and there is a decimal point. ex. there are three sig figs in 100. 1.00 and 10.0
The two numbers mentioned in the question have four significant figures (often called significant digits). If you wish to check your knowledge of sig-digs, check out the following link: http://science.widener.edu/svb/tutorial/sigfigures.html
15 000 894 written with 5 significant figures is 15 001 000, as the 894 rounds up to the nearest significant figure. 1.5001*10^7
001 has one significant digit, so the answer can only have one. 1.2 x 001 = 1

There is no moshling 001.
.001
It is 12 because 001 is the same as 1
The 0005 is larger without a decimal points. If you meant .001 and .0005, the .001 is larger.
Without a decimal point, they are both the same. If you asked "Which is less .01 or .001", then .001 is the smaller number.
