Using significant-digit rules, select all correct statements for (i) $6.5 - 6.32$ and (ii) $\frac{2.91 \times 0.3842}{0.080}$ .

Answer:

A, B, C

Solution:

In (i), subtraction is limited to the tenths place.

$6.5 - 6.32 = 0.18 ≃ 0.4$ at the justified precision.

In (ii), $0.080$ limits the result to two significant figures.

$\frac{2.91 ( 0.3842 )}{0.080} = 13.975275 \to 14$ .
