Question

determine the number of significant digits in 101.01

Explanation:

Step1: Recall significant digits rules

Significant digits include all non - zero digits, zeros between non - zero digits, and trailing zeros in a decimal number.

Step2: Analyze the number 101.01

• The non - zero digits are 1, 1, 1.
• The zero between the first and second 1 (in 101) is a zero between non - zero digits, so it is significant.
• The zero after the decimal point (in 101.01) is between non - zero digits (1 and 1 after the decimal) and is significant.

Now, let's count the significant digits: 1, 0, 1, 0, 1. So we have 5 digits.

Answer:

5
