@jim_thompson5910 is it A?

Answer 6

yes,

\[\Large p = \frac{|\text{approx} -\text{ exact}|}{\text{exact}} \times 100\%\]

\[\Large p = \frac{|5.23-6|}{6} \times 100\%\]

\[\Large p = \frac{|-0.77|}{6} \times 100\%\]

\[\Large p = \frac{0.77}{6} \times 100\%\]

\[\Large p \approx 0.128333 \times 100\%\]

\[\Large p \approx 12.8333\%\]
