Ask the student a question, and give any hints about how they should answer this part.

The length of a $\var{material}$ bar was estimated to be $\var{est}$ cm. If the true length was $\var{lent}$ cm, calculate the percentage error.

Unnamed gap%

Advice

Part 1:

Percentage error:

$abs(\frac{\var{est} - \var{lent}}{\var{lent}}) \times 100 = \var{ans1}$ %

Part 2:

Percentage error:

$abs(\frac{\var{est1} - \var{cost}}{\var{cost}}) \times 100 = \var{ans2}$ %

Part 3:

Percentage error:

$abs(\frac{\var{est2} - \var{att}}{\var{att}}) \times 100 = \var{ans3}$ %
