Question

How many significant figures should be present in the answer to the following calculation:-
$\frac{2.5\times 1.25\times 3.5}{2.01}$

Answer 1

$\frac{2.5\times 1.25\times 3.5}{2.01}=5.4415422885$

Since the least number of significant figures from the given numbers is 2 (in 2.5 and 3.5), the result should not have more than two significant figures.
Hence, No of Significant figures $=2$
