The significant zeros in the following numbers are given below;

  • 0.000067800 - all zeros except the last two
  • 3068800000 - all zeros
  • 4000600.00 - all zeros except the ones after the decimal point

<h3>What are significant zeros?</h3>

Significant figures of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something.

To determine whether or not a zero in a number is significant or not, the following rules are applied:

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

This suggests that the following applies to the following numbers;

  • 0.000067800 - all zeros except the last two
  • 3068800000 - all zeros
  • 4000600.00 - all zeros except the ones after the decimal point
