Explanation:
Detailed explanation-1: -We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit. We fill in any remaining places to the right of the decimal point with zeros.
Detailed explanation-2: -Example: Add 3.240 inches and 8.12 inches. 3.240 + 8.12 = 11.360, which has 3 significant digits in the decimal part.
