01.046
0.50
It has no significant zero because It is a leading zero
0.003 has one significant figure. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
0.7 has one significant figure. Any non-zero digit is significant (165 has three significant figures). Any zero between non-zero digits is significant (304 has three significant figures). Any zero to the right of a non-zero digit in a number which includes a decimal point is significant (10,000 has one significant figure, .0001 has one significant figure, but 100.0 has four significant figures, as does 0.001000). In this case, only the 7 is significant.
Left zero's are NOT significant: So it's one in 0.01
Any non-zero digit, if it appears in the decimal representation of a number, is significant. A zero is significant if it is not a leading zero.
3, one of the rules is counting the Zero between none zero numbers
7 of them. We're not exactly sure what that number is, but if it starts with a non-zero number and ends with a non-zero number, then everything's significant.
1.0070 has 5 significant figures. This is because when you are looking at a number with a decimal number, you start from the left and find a non-zero number. When you find the non-zero number, every number after it is significant.
1.200 has the greatest number of significant figures (four). 12000 has two significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
Only one of them is significant. The leading zero (zero to the left) is not significant. The trailing zero (rightmost) is significant. To recap, only the zero following the seven is significant. See the related links for a really good article on significant digits.
