To round .0966 to 2 significant digits, follow these steps:
Step 1: Identify the significant digits in the number. Significant digits are all the non-zero digits and any zeros between them. In this case, there are three significant digits: 9, 6, and 6.
Step 2: Determine the digit at the next position. In this case, the next digit is 0.
Step 3: If the next digit is less than 5, simply truncate (remove) all the digits after the desired significant digit. In this case, 0 is less than 5, so we round down and remove all the digits after the second significant digit. Thus, the number becomes .096.
If the next digit is 5 or greater, increase the desired significant digit by 1 and remove all the digits after it. For example, if the number was .0972, we would round up to .10.
In this case, since the next digit is 6 (greater than 5), we round up the last significant digit (6) becomes 7. Therefore, .0966 rounded to 2 significant digits is .097.
