Best answer

Answer - (3) 9.98m

 

Solution - 9.99 - 0.0099 = 9.9801

 

While performing addition or subtraction we have to assign the no.of significant figures in the answer based on the least no.of decimal digits in one of the measurement. Here 9.99 has the least no.of decimal digits, thus we should round off the answer to 2 decimal digits.

 

Thus, Answer = 9.98m
