For an experimental expression $y=\frac{32.3 \times 1125}{27.4}$, where all the digits are significant. Then to report the value of $y$ we should write
$y=1326.19$
$y=1330$
$y=1326.186$
$y=1326.2$
Solution
$y=\frac{32.3 \times 1125}{27.4}=1326.18$ So we need to report to three significant digit. So, $y=1330$
