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
- PGML location in OPL: FortLewis/Authoring/Templates/Algebra/FractionAnswer1_PGML.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 |
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 |
Context()->texStrings; BEGIN_SOLUTION ${PAR}SOLUTION:${PAR} Factor and cancel to obtain \( \displaystyle $answer \) END_SOLUTION Context()->normalStrings; ENDDOCUMENT(); |
Solution: |
