When determining the number of significant figures in a number, it’s important to understand the rules that apply. For the number 0.01, there is only 1 significant figure.
Here’s why:
- Leading zeros (zeros before the first non-zero digit) are not considered significant. In the number 0.01, the zeros before the digit 1 are leading zeros.
- Only the digit 1 is considered significant in this case.
Therefore, the number 0.01 has 1 significant figure.
