This PG code shows how to write a question in which the answer must be a fraction (rational number).
- File location in OPL: FortLewis/Authoring/Templates/Algebra/FractionAnswer1.pg
| PG problem file | Explanation |
|---|---|
|
Problem tagging: |
|
DOCUMENT(); loadMacros( "PGstandard.pl", "MathObjects.pl", "contextFraction.pl", "AnswerFormatHelp.pl", ); TEXT(beginproblem()); |
Initialization: |
Context("Fraction-NoDecimals");
$answer = Compute("3/2");
|
Setup:
The macro Context("Fraction");
Context("Fraction-NoDecimals");
Context("LimitedFraction");
Context("LimitedProperFraction");
For the differences among these, see the POD documentation contextFraction.pl.html |
Context()->texStrings;
BEGIN_TEXT
Simplify \( \displaystyle \frac{6}{4} \).
$BR
$BR
Answer =
\{ ans_rule(20) \}
\{ AnswerFormatHelp("fractions") \}
END_TEXT
Context()->normalStrings;
|
Main Text: |
$showPartialCorrectAnswers = 1; ANS( $answer->cmp( studentsMustReduceFractions=>1, reduceFractions=>1, allowMixedNumbers=>0, ) ); |
Answer Evaluation: There are many context flags that control how fraction answers are checked. See the POD documentation contextFraction.pl.html |
Context()->texStrings;
BEGIN_SOLUTION
${PAR}SOLUTION:${PAR}
Factor and cancel to obtain
\( \displaystyle $answer \)
END_SOLUTION
Context()->normalStrings;
ENDDOCUMENT();
