The precision is determined by the POSITION of the number 6 - NOT its value.
8
4082 Since the tens digit is 2 times the thousand digit, it must be an even digit. So it can be 8, 6, 4, or 2. But, the thousands digit is 4 greater than the hundred digit. So that the hundred digit must be 0, the thousands digit must be 4, the hundreds digit must be 8, and the ones digit must be 2.
the leading digit
first digit time second digit and second digit times first digit then repeat
1346
In this case with 234.896 the last digit, '6' determines the precision since in is the last non-zero digit.
7
It has no precision, since there is no following number.
3
7
The last digit, 2.
There a four significant figures in the number 16.82, the last '2' determines the best precision available.
2
The "2".
4
3
In the number 10.846, the digit that determines its precision is the last digit, which is 6. This is because precision refers to the level of detail in a measurement, and the last significant digit indicates the smallest unit of measurement being reported. Therefore, the presence of the digit 6 suggests that the value is precise to the thousandths place.
