- The integers 1,2,3,4,5,6,7,8,9 are always significant
- Zeros in between numbers are always significant
Explanation:
The rules to determine whether a digit is significant or not are the following:
- All the non-zero digits are significant: 1,2,3,4,5,6,7,8,9
- The zeros between two non-zero numbers are always significant
- The zeros before non-zero numbers on the left of the decimal point are never significant
- The zeros given after a non-zero number on the right of the decimal point are significant if they provide information about the precision of the measure
So now let's analyze the statements given:
- The integers 1,2,3,4,5,6,7,8,9 are always significant --> true
- All numbers to the right of the decimal point are always significant --> false. For instance, in 0.012, only 1 and 2 are significant.
- Zeros to the left of a decimal point and in a number greater than or equal to 10 are always significant --> false. For instance, in 7200, the two zeros are not significant.
- All zeros are significant numbers --> false, as we saw in the previous examples
- Zeros in between numbers are alwasy significant --> true
