Expert Answer

Step 1

The significant figures can be defined as the digits in the given number that carry some meaning and are also contributing to its measurement resolution.

Step 2

  • Non-zero digits are always significant.
  • Any zeros between two significant digits are significant
  • A final zero or trailing zeros in the decimal portion only are significant.
Step 3

 To round off the number, below listed rules should be followed;

  • The last figure should be unchanged if the first figure dropped is less than 5.
  • The last figure should be increased by 1 if the first figure dropped is greater than 5.
  • If the first figure dropped is 5, and all the figures following the five are zero, then the last figure should be unchanged if that last figure ...
