हिन्दीEvaluate the sum \( 436.32 \text{ g} + 227.2 \text{ g} + 0.301 \text{ g} \) by properly considering the rules of significant figures and decimal places in addition.
Correct answer · Option 2
\( 663.8 \text{ g} \)
Explanation
In addition or subtraction, the final result should retain as many decimal places as are there in the number with the least decimal places (227.2 has 1 decimal place). Thus 663.821 g rounds off to 663.8 g.
