To express 0.0781 to one significant figure, you focus on the first non-zero digit, which is 7. Thus, rounding 0.0781 to one significant figure gives you 0.08, as you need to maintain the same decimal place.

To express 124.683 with one significant digit, we round it to the nearest ten. The first significant digit is '1' in the hundreds place, so we round 124.683 to 100.
1. The rest are just place holders.
3. Any number that is not a 0 is a significant number. Rules for Significant Figures: 1. Non-zero numbers are always significant. (example: 1-9) 2. Zeroes between non-zeroes are always significant. (ex: the zero in 908 is significant) 3. All final zeroes to the far right of the decimal place are significant. (ex: the zeroes in 34.0 and 7.0 is significant) 4. Zeroes that act as place holders are not significant. (ex: the zeroes in 600 are not significant) 5. Zeroes before a decimal act as place holders and are not significant. (ex. the zero in 0.12 is not significant)
0.009 rounded to one decimal place is 0.0. Since the first decimal place is 0 and there are no significant figures beyond that, it remains as 0.0.

849 to 1 significant figure is 800. This is because the first non-zero digit is 8, so the significant figure is the hundreds place.

370.0 has four significant figures, because the last zero indicates the precision of the number (to 1 decimal place).
no it contains 4 significant figures. and 1 decimal place. a significant number is every number written down including zero if after an integer
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
When rounding 7463 to 2 significant figures, we look at the digit in the hundred's place, which is 4. Since the digit immediately to the right of the hundred's place is 6, which is 5 or greater, we round up the hundred's place digit by 1. Therefore, 7463 rounded to 2 significant figures is 7500.
Seven: starting with the 1 and ending with the 0 in the thousandths place..
