\begin{aligned} E_{pct} &= \dfrac{|x_{obs} - x_{true}|}{|x_{true}|} \times 100\% \\ &= \dfrac{|(9.8) - (10)|}{|10|} \times 100\% \\ &= ?\% \end{aligned}
\begin{aligned} E_a &= x_{obs} - x_{true} \\ &= (9.8) - (10) \\ &= ? \end{aligned}
\begin{aligned} E_r &= \dfrac{|x_{obs} - x_{true}|}{|x_{true}|} \\ &= \dfrac{|(9.8) - (10)|}{|10|} \\ &= ? \end{aligned}
