Question

Why does 4.03/0.0000035 = 1.2 x 106, instead of a different number of significant figures?

Answer 1

Explanations:- As per the significant figures rule, In multiplication and division, we go with least number of sig figs.

4.03 has three sig figs where as 0.0000035 has two sig figs only, The zeros in this number are not sig figs as they are just holding the place values. As the least number of sig figs here is two, the answer needs to be reported with two sig figs only.

$\frac{4.03}{0.0000035}=1.2*10^6$
