हिन्दीAccording to the rules of arithmetic operations with significant figures, what is the sum of \( 436.32\text{ g} \), \( 227.2\text{ g} \), and \( 0.301\text{ g} \)?
Correct answer · Option 2
663.8 g
Explanation
In addition or subtraction, the final result should retain as many decimal places as the number with the least decimal places (\( 227.2\text{ g} \) has 1 decimal place). Thus, \( 663.821\text{ g} \) is rounded off to \( 663.8\text{ g} \).
